Description of Partition Wall Bricks and Their Preparation Method Technical Field This application belongs to the field of building engineering technology, and particularly relates to a partition wall brick and its preparation method. 5. Background Technology With the advancement of low-carbon construction, the supply of basic raw materials such as virgin aggregates and cement in the building materials industry is tightening, and the problem of raw material shortage is becoming increasingly prominent. At the same time, the volume of waste glass generated by urban construction is enormous, covering various categories such as glass bottles, curtain wall glass, and automotive glass. The resource utilization rate of this type of solid waste is low, and solid waste disposal and environmental protection have become common problems in the industry. Existing research has confirmed that waste glass can be processed into waste glass powder and waste glass aggregate for use in the building materials field. Among them, waste glass powder can partially replace cement, and waste glass aggregate can replace crushed stone. This not only enables low-carbon production of building materials, but also optimizes the erosion resistance and shrinkage resistance of concrete, improves material durability, and has broad prospects for resource utilization. 15 Currently, the application technology of waste glass in building partition wall bricks still has shortcomings, and existing products are difficult to achieve both high strength and high fire resistance. Against the backdrop of increasingly stringent fire safety requirements in the building industry, the fire resistance of partition wall bricks is directly related to the overall fire resistance of buildings. Therefore, developing waste glass partition wall bricks that combine high strength and high fire resistance is a technical challenge that urgently needs to be solved in this field. 20 Summary of the Invention In view of this, embodiments of this application provide a partition wall brick and its preparation method to solve the technical problem that existing partition wall bricks are difficult to achieve both high strength and high fire resistance.

HK 30138176 A 3 In some embodiments, treating glass aggregate with a water-soluble additive to obtain modified glass aggregate comprises: weighing an appropriate amount of water-soluble additive and dispersing it in water, stirring evenly to obtain a water-soluble additive dispersion; mixing the water-soluble additive dispersion with glass aggregate according to a preset ratio, drying to obtain modified glass aggregate. 5. In some embodiments, the weight ratio of the water-soluble additive dispersion to the glass aggregate is 1:10~20.

In traditional existing building partition brick preparation technology, when waste glass is used as a raw material, it faces the technical problem of insufficient strength and fire resistance. The essence of this problem lies in the low bonding strength of the interface transition zone between waste glass aggregate and cement matrix. Under high-temperature environments, interface bonding failure is induced, leading to damage to the structural integrity of the partition brick. As a result, the partition brick cannot meet the stringent fire resistance requirements of building engineering, adversely affecting the overall fire resistance of the building. For example, in the construction of partition walls in high-rise commercial buildings, partition bricks prepared from conventional waste glass aggregate are used for wall masonry. Under simulated fire conditions, cracking was observed in the interface area of ​​the partition wall bricks, resulting in a decrease in strength parameters, weakened structural stability, and an inability to effectively prevent the spread of fire, thus threatening the safety of the building's interior. The weak interface transition zone between the waste glass aggregate and the cement matrix was further exposed under high temperatures, causing the partition wall bricks to fail to meet building safety standards in fire scenarios. If the weakness in the interface transition zone is not addressed, the structural stability of the partition wall bricks under fire conditions will be compromised, potentially leading to an overall decrease in the building's fire resistance, increased fire risk, and impacting the long-term safety and reliability of the building structure. Therefore, developing a technical solution to effectively enhance the bonding strength of the interface transition zone is essential. To address this technical problem, the first aspect of this application provides a partition wall brick comprising the following components in parts by weight: 60-80 parts of main aggregate; 15-25 parts of glass aggregate; 6-8 parts of cement; 1.2-4 parts of glass powder; and 0.01-0.05 parts of water-soluble additives. The main aggregate includes at least one of recycled waste concrete aggregate and natural crushed stone aggregate, and the glass aggregate and glass powder are derived from waste glass. In the preparation of traditional partition wall bricks, there is usually a heavy reliance on natural aggregates and pure cement, leading to excessive consumption of natural resources and high carbon emissions. For example, in the above example, if only natural crushed stone aggregate and pure cement without glass powder are used, although basic strength can be obtained, its environmental friendliness is poor, and there may be limitations in fire resistance.This embodiment achieves effective utilization of construction and industrial waste by introducing recycled aggregate from waste concrete as part of the main aggregate and preparing glass aggregate and glass powder from waste 10 glass. For example, in this example, recycled aggregate from waste concrete is mixed into the main aggregate, while the glass aggregate and glass powder are entirely derived from waste glass. This material substitution strategy significantly reduces dependence on native resources compared to the use of natural materials alone in existing technologies, aligning with the concept of sustainable development. Furthermore, the key to this embodiment lies in the synergistic effect of glass powder and water-soluble additives. In this example, 15 glass powder, as a supplementary cementitious material, has a fineness that allows it to participate in the hydration reaction of cement, forming more hydration products, thereby improving the density and strength of the partition wall bricks. Compared to the use of cement alone as a cementitious material in existing technologies, the introduction of glass powder not only reduces cement usage but also improves the long-term performance of the material through its pozzolanic activity. More importantly, water-soluble additives play multiple key roles in this embodiment. In the example, additive 20 not only improves the dispersibility of aggregates, but more importantly, it modifies the interface of glass aggregates, promoting the hydration and carbonization processes of cement and glass powder. This interface modification and promoting effect strengthens the interfacial transition zone between glass aggregates and cement / glass powder, effectively solving the problems of alkali-silica reaction and poor interfacial bonding that may exist in waste glass in cement-based materials. Compared with the problems of weak bonding between glass aggregates and matrix and easy cracking that may exist in the prior art, this embodiment significantly improves the overall strength and durability of the partition wall bricks by introducing water-soluble additive 25. HK 30138176 A 7 Thus, through the optimized combination of main aggregates, the refined utilization of waste glass, and the interface enhancement and reaction promoting effect of water-soluble additives, the partition wall bricks of this embodiment not only effectively solve the problem of resource utilization of waste glass, but also significantly improve in terms of strength, density, and fire resistance. This comprehensive technical solution provides an innovative and feasible way to develop high-performance, environmentally friendly partition wall bricks, and has important technological progress significance. 5. For ease of understanding, the following explains some key terms in this embodiment: Partition wall bricks generally refer to masonry materials used for non-load-bearing walls inside buildings. Their main functions are to separate spaces, provide sound insulation, heat insulation, and offer certain fire resistance. Main aggregate is the main filler material in partition wall bricks, typically providing structural support and volume filling. In this embodiment, the main aggregate may include at least one of the following: recycled waste concrete aggregate and natural crushed stone aggregate, which helps to balance material performance and resource utilization. Glass aggregate refers to granular materials formed from waste glass after crushing, screening, and other processing. Using glass aggregate as aggregate in partition wall bricks can replace some natural aggregate, realizing the reuse of waste resources.Cement, an important cementitious material, binds aggregates together through hydration to form a hardened body with a certain strength. In partition wall bricks, it plays a role in providing early strength and long-term stability. Glass powder refers to a powdered material formed from finely ground waste glass. This glass powder can act as a supplementary cementitious material, working together with cement to participate in the hydration reaction and potentially improving the microstructure of the material. Water-soluble additives are chemicals that can dissolve in water and have a specific effect on the performance of partition wall bricks. In this embodiment, the water-soluble additive is used to improve the interfacial properties of the aggregates and promote the hydration and carbonation of the cementitious material, thereby improving the overall performance of the partition wall bricks. Recycled aggregate from waste concrete refers to aggregate obtained after waste concrete has been crushed and screened. As a primary aggregate, it helps reduce construction waste and achieve recycling. Natural crushed stone aggregate refers to aggregate obtained by mining natural rock and then crushing and screening it. As a traditional building material, it has good mechanical properties. HK 30138176 A 8 Waste glass refers to various unused glass products, such as waste glass bottles, curtain wall glass, automobile windshields, light tube glass, and glassware. Recycling and reusing these materials to produce glass aggregate and glass powder is an important way to achieve resource utilization in this embodiment. In application, this embodiment provides a partition wall brick, which aims to optimize performance through specific component ratios and material selection. The components of the partition wall brick include main aggregate, glass aggregate, cement, glass powder, and water-soluble additives. The main aggregate has a weight ratio of 60-80 parts. The main aggregate can be natural crushed stone aggregate alone, which has good strength and stability, but may have problems with high resource consumption and mining costs. Alternatively, the main aggregate can be recycled waste concrete aggregate alone, which helps with resource recycling, but may be slightly inferior to natural crushed stone aggregate in some performance aspects. Natural crushed stone aggregate and recycled waste concrete aggregate can also be mixed to balance performance and cost. 10. The glass aggregate comprises 15-25 parts by weight. This glass aggregate can be obtained from waste glass through simple crushing and screening, and its particle size distribution can be relatively wide. For example, glass fragments with a particle size of 1-5 mm can be used as glass aggregate. This processing method is relatively simple and low-cost, but it may result in insufficient surface activity of the glass aggregate, and the bonding strength with the cement matrix needs to be improved. 15. The cement comprises 6-8 parts by weight. As the main cementitious material, the type of cement can be ordinary Portland cement commonly available on the market. Ordinary Portland cement has good early strength and general applicability, but its hydration products may be highly sensitive to the alkali-silica reaction of the glass aggregate. 16. The glass powder comprises 1.2-4 parts by weight. This glass powder can be obtained from waste glass through grinding, and its fineness can be controlled to, for example, below 100 μm.This glass powder can be used as a supplementary cementitious material to participate in the hydration reaction, but if the fineness is insufficient, its pozzolanic activity may not be obvious, and its improvement on material performance will be limited. The water-soluble additive is 0.01~0.05 parts by weight. Water-soluble additives are used to treat glass aggregates to achieve interface reinforcement and improve fire resistance. It promotes the hydration and carbonation of cementitious materials, strengthens the interface transition zone between glass aggregates and mortar, and enables the internal structure of the partition wall bricks to remain stable under high temperatures. The main aggregate includes at least one of waste concrete recycled aggregate and natural crushed stone aggregate. For example, only natural crushed stone aggregate can be used as the main aggregate to ensure the basic mechanical properties of the partition wall bricks. Alternatively, only waste concrete recycled aggregate can be used as the main aggregate to maximize the utilization rate of waste. In application, the raw materials may also include 1~2 parts of steel slag. The addition of steel slag to this formula optimizes the overall gradation based on its reasonable particle morphology, conforms to the particle packing theory, fills the internal voids of the matrix, and improves the density of the partition bricks. Steel slag possesses potential hydration activity, which can assist in the cementing process, replacing part of the cement raw materials and effectively reducing production costs. Simultaneously, steel slag exhibits excellent high-temperature resistance, compensating for the insufficient heat resistance of waste glass, significantly improving the fire resistance and high-temperature structural stability of the products, and reducing high-temperature deformation cracking. Furthermore, steel slag can improve the volume stability of the bricks, inhibit drying shrinkage, enhance long-term durability, and synergistically promote carbonization curing reactions, accelerating strength forming, achieving the dual utilization of steel slag and waste glass as industrial solid waste resources, further practicing the low-carbon manufacturing concept. In some embodiments, waste glass is washed, screened, and ground to obtain glass aggregate and glass powder, wherein the particle size of the glass aggregate is 0.15~10mm, and the particle size of the glass powder is less than 150μm. Specifically, the glass aggregate has particle sizes of 0.15mm, 1mm, 2mm, 3mm, 5mm, 6mm, 8mm, and 10mm, with the particle size range limited to 0.15~10mm. This is designed to ensure that it can function as a skeleton in the partition wall bricks, providing sufficient strength and stability. Glass aggregate within this particle size range can effectively fill the voids between the main aggregates, forming a dense aggregate gradation, while avoiding stress concentration within the partition wall bricks due to excessively large particle sizes or affecting the load-bearing capacity of the aggregates due to excessively small particle sizes. For example, fine aggregates with a particle size of 0.15-5mm and coarse aggregates with a particle size of 5-10mm can be combined to optimize the gradation. The glass powder has a particle size of less than 150μm, designed to ensure sufficient fineness so that it can function as an active admixture or microfiller in the partition wall bricks. Finer glass powder can increase the specific surface area, promote the hydration reaction with cement, and form more hydration products, thereby improving the strength and durability of the partition wall bricks.Meanwhile, fine glass powder particles can fill the tiny gaps between aggregates, improving the material's density. The proposed solution, through cleaning waste glass, thoroughly removes various impurities from its surface, preventing these impurities from forming weak interfaces or introducing harmful substances within the partition bricks. This ensures the purity of the glass aggregate and glass powder, providing a good foundation for subsequent cementing reactions and aggregate interlocking. Subsequently, through screening and grinding processes, the cleaned waste glass is precisely processed into glass aggregate and glass powder within a specific particle size range. The particle size of the glass aggregate is controlled between 0.15 and 10 mm, allowing it to form a good gradation with the main aggregate, constructing a stable skeletal structure within the partition bricks, effectively bearing the load, and reducing material shrinkage and cracking. Meanwhile, glass powder with a particle size of less than 150 μm, due to its larger specific surface area, can participate more fully in the hydration reaction of cement, acting as an active admixture to promote secondary hydration and generate more hydrated calcium silicate gel, thereby significantly improving the density, strength, and durability of the partition wall bricks. Furthermore, the fine glass powder particles can effectively fill the tiny gaps between aggregates, further optimizing the pore structure of the material. This refined waste glass treatment method ensures that the quality and performance of both glass aggregate and glass powder meet expectations, enabling them to work synergistically with cement, main aggregates, and water-soluble additives to jointly construct high-performance partition wall bricks, effectively overcoming the performance instability problems that may arise from untreated waste glass. In some embodiments, the weight of glass powder accounts for 10% to 50% of the cement mass. Specifically, the weight of glass powder in the cement mass can be 10%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, etc. The solution of this application precisely controls the weight of the glass powder within the range of 10% to 50% of the cement mass, allowing the glass powder to fully exert its pozzolanic activity. Under this optimized ratio, the active silica in the glass powder can undergo a secondary reaction with calcium hydroxide in the alkaline environment generated by cement hydration, generating more hydrated calcium silicate gel. These secondary hydration products not only fill the pores in the cement paste, increasing its density, but also enhance the interfacial transition zone between the cement matrix and the aggregate, thereby improving the overall mechanical properties and durability of the partition wall bricks. In some embodiments, natural crushed stone aggregate or recycled waste concrete aggregate is embedded in and encapsulates the glass aggregate to form a compatible structure, with the glass aggregate accounting for 20% to 60% of the total mass of the main aggregate and the glass aggregate. The solution of this application achieves effective encapsulation of the glass aggregate by rationally proportioning and mixing natural crushed stone aggregate or recycled waste concrete aggregate with the glass aggregate.This interlocking action physically fixes and constrains the glass aggregate throughout the aggregate system. Even if the chemical bond between the glass aggregate and the cement matrix is ​​relatively weak, stress can be transferred through mechanical interlocking. Simultaneously, the specific proportion (20%~60%) of glass aggregate in the main aggregate and the total mass of glass aggregate is optimized, ensuring the formation of a stable and sufficiently strong aggregate skeleton while fully utilizing 25% waste glass resources. This structure not only enhances the overall connectivity between aggregates and reduces stress concentration caused by poor aggregate interface bonding, but also helps to evenly distribute external loads throughout the partition brick, thereby significantly improving the compressive strength, flexural strength, and durability of the partition brick. In some embodiments, water-soluble additives modify the interface of the glass aggregate, promoting the hydration and carbonization of the cement and glass powder, achieving a strengthened interface transition zone between the glass aggregate and cement / glass powder, and improving fire resistance. The present application employs a water-soluble additive to surface-treat glass aggregate, transforming the surface of the glass aggregate from inert to active, thereby significantly improving the interfacial compatibility between the glass aggregate and the cement / glass powder matrix. This interfacial modification not only enhances the physicochemical bonding between the glass aggregate and cement hydration products but also reduces the porosity and defects in the interfacial transition zone. Simultaneously, the water-soluble additive promotes the hydration reaction of cement and the carbonization reaction of glass powder, resulting in a denser cement matrix and generating more cementitious material to fill the interfacial transition zone. This dual-action mechanism leads to a significant enhancement of the interfacial transition zone between the glass aggregate and cement / glass powder. A high-strength, high-density interfacial transition zone effectively resists thermal stress and inhibits the initiation and propagation of microcracks at high temperatures, thus enabling the partition wall bricks to maintain better structural integrity and load-bearing capacity under fire conditions, significantly improving their fire resistance. In some embodiments, the water-soluble additive includes one of sodium gluconate, sodium melamine-formaldehyde resin sulfonate, sodium methylsilicate, sodium ethylsilicate, and anhydrous ethanolamine. Water-soluble additives can include sodium gluconate, which acts as a retarder and water-reducing agent, improving the workability of the mixture and optimizing the crystal structure of cement hydration products; sodium melamine-formaldehyde resin sulfonate, which acts as a high-efficiency water-reducing agent, significantly reducing water consumption and increasing the density of the cement matrix; sodium methylsilicate or sodium 20-ethylsilicate, which act as silane coupling agents, reacting with the hydroxyl groups on the surface of glass aggregate to form chemical bonds and enhance interfacial bonding; or anhydrous ethanolamine, which acts as an alkaline activator, promoting the pozzolanic reaction of glass powder. In some embodiments, the cement includes one of ordinary Portland cement, composite Portland cement, and slag Portland cement.Cement, as a key cementitious material in partition wall bricks, has a decisive influence on the mechanical properties, durability, hydration characteristics, and interfacial bonding performance with aggregates of the partition wall bricks. Ordinary silicate cement, with its good early strength and wide applicability, can provide a solid foundation structure for partition wall bricks. Composite silicate cement, by incorporating various active admixtures, can effectively improve the later strength, impermeability, and carbonation resistance of partition wall bricks, and help reduce the heat of hydration, thereby improving the long-term stability of the material. Slag silicate cement utilizes industrial waste as an admixture, which not only has significant environmental benefits but also improves the sulfate resistance and later strength of partition wall bricks, extending their service life. In some embodiments, waste glass includes at least one of waste glass bottles, curtain wall glass, automotive windshields, light tube glass, and glassware. Waste glass is the source of glass aggregates and glass powder in this application, and it is diverse in type, with varying chemical compositions and physical properties. Waste glass bottles are typically made of soda-lime glass, which is easy to recycle and has a relatively stable composition. Curtain wall glass and automotive windshields may contain laminates or special coatings, but after proper pretreatment, their glass body can still be used as high-quality aggregate or powder. Although fluorescent tube glass may contain small amounts of heavy metals, after cleaning and grinding, its main component is still silicate, which can be safely utilized. Glassware encompasses a variety of glass products, and its recycling helps broaden the sources of waste glass and reduce environmental pollution. Secondly, this application proposes a method for preparing partition wall bricks, including the following steps: S10, providing the above-mentioned raw materials, as shown in Figure 1; S20, treating the glass aggregate with water-soluble additives to obtain modified glass aggregate; S30, mixing cement and glass powder to obtain a cementitious material; S40, mixing the cementitious material, modified glass aggregate, and main aggregate, adding water after uniform mixing, continuing to stir, filling a mold, vibrating and compacting, and demolding and curing to obtain partition wall bricks. Specifically, this application combines the interface modification of glass aggregate with water-soluble additives with the mixing process of cement and 20% glass powder, effectively enhancing the interfacial transition zone between glass aggregate, cement, and glass powder. Given that waste glass easily triggers alkali-silica reactions in cement-based materials, leading to poor interfacial bonding and significantly reducing the fire resistance of partition wall bricks, this application's solution promotes the hydration and carbonization processes of cement and glass powder through water-soluble additives, making the structure of the interfacial transition zone denser and more stable. Since insufficient fire resistance during the resource utilization of waste glass is a key bottleneck restricting its application in partition wall bricks, this application, through the above-mentioned technical means, not only achieves efficient resource utilization of waste glass but also significantly improves the overall fire resistance and strength of partition wall bricks, meeting the comprehensive requirements of building engineering for partition wall materials in terms of strength, durability, and fire resistance.In some embodiments, the step of treating glass aggregate with a water-soluble additive to obtain modified glass aggregate includes: weighing an appropriate amount of water-soluble additive and dispersing it in water, stirring evenly to obtain a water-soluble additive dispersion; mixing the water-soluble additive dispersion with the glass aggregate according to a preset ratio, and drying to obtain the modified glass aggregate. The solution of this application, by pre-dispersing the water-soluble additive in water to prepare a uniform dispersion, and then thoroughly mixing the dispersion with the glass aggregate, ensures that the water-soluble additive can uniformly and comprehensively adhere to the surface of the glass aggregate. This refined treatment method allows the water-soluble additive to fully exert its interface modification effect, promoting the hydration and carbonization of cement and glass powder, and enhancing the interface transition zone between the glass aggregate and cement / glass powder, thereby improving the fire resistance of the partition wall bricks. The subsequent drying step further stabilizes the modified layer on the surface of the glass aggregate, removes excess moisture, avoids potential negative impacts during subsequent mixing and hydration processes, and ensures the durability of the modification effect and the stability of the overall performance of the partition wall bricks. This treatment method, combined with the aforementioned preparation method for partition wall bricks, allows the glass aggregate to better integrate with the cementitious material system, thereby significantly improving the overall performance of the partition wall bricks. Specifically, the step of weighing an appropriate amount of water-soluble additive and dispersing it in water, then stirring it evenly to obtain a water-soluble additive dispersion, aims to prepare the water-soluble additive in a liquid form that is easy to contact and react with the glass aggregate. Water-soluble additives usually exist in the form of solid powder or concentrated liquid, and may be difficult to disperse evenly if used directly. By dispersing it in water and stirring it thoroughly, a uniform solution or suspension can be formed, ensuring that the additive can fully and evenly cover the surface of the glass aggregate during subsequent processing. The step of mixing the water-soluble additive dispersion with the glass aggregate in a preset ratio is the core step in achieving interface modification of the glass aggregate. By thoroughly mixing the prepared water-soluble additive dispersion with the glass aggregate, the additive can be evenly adhered to the surface of the glass aggregate, thereby achieving effective interface modification. The aforementioned preset ratio is 1:(10~20), specifically 1:10, 1:12, 1:14, 1:17, 1:18, 1:20, etc. The solution in this application precisely controls the weight ratio of the water-soluble additive dispersion to the glass aggregate within the range of 1:(10~20), ensuring that the water-soluble additive can act on the surface of the glass aggregate with optimal concentration and coverage. When the water-soluble additive dispersion and the glass aggregate are mixed according to this specific ratio, the water-soluble additive can be uniformly adsorbed or reacted on the surface of the glass aggregate, forming a modified layer.This modified layer effectively improves the surface activity and hydrophilicity of the glass aggregate, enabling it to better integrate with the cementitious material system when subsequently mixed with cement and glass powder. Precise proportion control avoids incomplete modification due to insufficient additives, and also avoids increased costs and potential negative impacts on material properties caused by excessive additives. In this way, the modified glass aggregate can more effectively promote the hydration and carbonation reactions of cement and glass powder, thereby forming an enhanced interfacial transition zone between the glass aggregate and cement / glass powder, significantly improving the overall strength and durability of the partition wall bricks, and further enhancing their fire resistance. In some embodiments, the curing treatment in the above preparation method includes either standard curing or carbonization curing. Curing treatment is a series of measures taken after the cement-based material product is formed to ensure its continued development of strength and durability. Its function is to provide suitable temperature and humidity conditions for cement hydration, ensuring the cement hydration reaction proceeds fully, thereby densifying the internal structure of the material and improving the mechanical properties and durability of the product. In addition to the standard curing and carbonation curing mentioned in this application, curing treatments can also include steam curing, atmospheric pressure steam curing, and high pressure steam curing, to adapt to different production needs and material properties. Standard curing refers to curing cement-based material products under specified temperature and humidity conditions to ensure their performance develops in a stable and controllable environment. This curing method typically simulates ideal conditions in the natural environment, aiming to promote full hydration of cement, thereby achieving stable strength growth and good durability. Standard curing can be implemented by placing the products in a curing chamber with automatic temperature and humidity control, or in a laboratory environment with constant temperature and humidity. Carbonation curing is a curing method that utilizes the reaction of carbon dioxide with cement hydration products (such as calcium hydroxide) to produce calcium carbonate. This reaction can accelerate the early strength growth of materials and help solidify carbon dioxide, offering certain environmental benefits. Carbonation curing can be implemented by placing the products in a sealed carbonation chamber, introducing a certain concentration of carbon dioxide gas, and controlling the temperature and pressure inside the chamber to optimize the efficiency and depth of the carbonation reaction. HK 30138176 A 15 In application, the standard curing conditions include: curing in a standard curing chamber at a temperature of 20~30℃ for 24~28 days. By selecting standard curing, it can be ensured that the partition bricks undergo sufficient hydration reaction under stable temperature and humidity conditions of 20~30℃, with a curing time of 24~28 days, thereby reliably improving the strength and durability of the cement-based material and forming a uniform and dense internal structure. The carbonation curing conditions include: a curing time of 1~3 days, a carbonation temperature of 25℃~30℃, and a carbonation pressure of 0.1~1 bar.Carbonation curing allows for a shorter curing time of 1-3 days, utilizing carbon dioxide to react with cement hydration products. Under conditions of 25℃-30℃ carbonation temperature and 0.1-1 bar carbonation pressure, it accelerates the early strength development of partition wall bricks. Carbonation curing not only significantly shortens the curing cycle and improves production efficiency, but also, the calcium carbonate generated by the carbonation reaction fills the material pores, further improving the density and strength of the partition wall bricks. Simultaneously, it solidifies carbon dioxide, demonstrating environmental friendliness. Through the above technical solutions, the preparation method of partition wall bricks allows for flexible selection of curing methods based on actual production needs and product performance targets. Standard curing ensures stable long-term strength and excellent durability of the partition wall bricks, guaranteeing product quality reliability. Carbonation curing, on the other hand, significantly shortens the curing cycle while accelerating the early strength development of the partition wall bricks, improving production efficiency, and utilizing carbon dioxide for solidification, reducing environmental impact. This selective curing strategy makes the production process of partition wall bricks more adaptable and economical, effectively solving the limitations of traditional curing methods in terms of efficiency and performance optimization. Thus, while ensuring the performance of the partition wall bricks, it achieves optimized production processes and efficient resource utilization. The partition wall bricks and their preparation method provided in this application fully utilize waste glass as a building material, not only realizing the recycling and reuse of waste glass but also reducing the amount of natural building materials such as crushed stone aggregate and cement, which is conducive to achieving the "dual carbon target." Through specific gradation design, the partition wall bricks achieve high strength and high fire resistance, enabling them to meet the application requirements of building engineering and broadening the application scope of recycled glass. Through carbonization curing technology, a carbonization curing production chain for the recovery and utilization of industrial exhaust CO2 is constructed, forming a complete carbonization curing process, further promoting carbon reduction and truly realizing the development of negative carbon building materials. Compared with traditional partition wall bricks, it has higher economic and environmental benefits. 25 This partition wall brick is a green and environmentally friendly brick prepared based on a dual strategy of raw material gradation design and interface optimization (HK 30138176 A 16). First, high-performance glass powder cementitious material (cement + glass powder) is used to enhance the bonding ability between aggregates. Then, the glass aggregate content is determined based on the gradation optimization design method. Finally, an accelerated carbonization curing technology is used to form a partition wall brick combining glass powder cementitious material and glass aggregate. Waste glass is the main raw material for the partition wall brick, and its sources include waste glass bottles, curtain wall glass, automotive windshields, light tube glass, and tableware glass. Waste glass can be ground into micron-sized glass powder to replace part of the cement, or it can be crushed into glass aggregate for use as aggregate.In the material gradation design process, the theory of densest particle packing and the modified Andreasen & Andersen model were adopted to determine the proportions of each raw material. Interface treatment of the glass aggregate was performed using admixtures to enhance the interface transition zone and improve refractory performance. During the carbonization and curing stage, industrial boiler exhaust gas (CO2) was used to construct an accelerated carbonization and curing production chain. By controlling the carbonization and curing parameters, a partition brick combining glass powder cementitious material and glass aggregate was obtained. Its strength and refractory performance meet the requirements of building engineering and can be applied to building partitions and other applications. Example 1 This example provides a partition wall brick and its preparation method. The preparation method includes the following steps: S10, as shown in Figure 1, provide 70kg of waste concrete recycled aggregate, 20kg of glass aggregate, 158.0kg of cement, 2.0kg of glass powder, and 0.024kg of water-soluble additive; S20, add 0.024kg of water-soluble additive to 2kg of water, stir evenly, and then mix it evenly with the above glass aggregate at a ratio of 1:10. Dry it under natural conditions to obtain modified glass aggregate; S30, mix cement and glass powder to obtain cementitious material; S40, mix cementitious material, modified glass aggregate and waste concrete recycled aggregate, mix evenly, add water and continue stirring. After stirring evenly, put it into a mold, stir for 3 minutes, vibrate to compact and demold. Place the prepared partition wall brick in a standard curing box for curing at a curing temperature of 25℃ for 28 days to obtain the partition wall brick, as shown in Figure 2. Example 2 The materials, proportions, and preparation process used in Example 2 are the same as in Example 1. The difference lies in the curing method. In Example 2, the curing method is carbonization curing, the curing age is 2 days, the carbonization temperature is HK 30138176 A 17 30℃, and the carbonization pressure is 0.5 bar. Example 3 Example 3 is based on Example 1, but with a different cementitious material proportion. All other preparation processes and curing methods are exactly the same. The cementitious material proportion in Example 3 is as follows: cement 6.20 kg, steel slag 1.77 kg, and glass powder 2.03 kg. 5. Performance Testing and Test Results 1.
