Description

Technical Field

[0001] This utility model relates to the field of concrete technology, specifically to a frost-resistant and crack-resistant concrete structure. Background Technology

[0002] Concrete is one of the most important civil engineering materials in modern times. It is an artificial stone material made by mixing cementitious materials, granular aggregates (also known as aggregates), water, and, when necessary, admixtures and additives in a certain proportion, uniformly mixing, compacting, and curing. With the continuous improvement of modernization, its usage is also increasing. It is used not only in various civil engineering projects, but also in shipbuilding, machinery industry, marine development, geothermal engineering and other fields. Therefore, the performance requirements for concrete are also getting higher and higher.

[0003] However, existing concrete structures face two major challenges: frost resistance and crack resistance. In cold climates, the moisture inside concrete is prone to freezing and expansion, which causes stress within the structure and leads to cracks. These cracks not only affect the aesthetics of the structure, but more importantly, they reduce the overall strength, stability, and durability of the structure. Therefore, we propose a frost-resistant and crack-resistant concrete structure to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] like Figure 1-3 As shown in the figure, an embodiment of this utility model proposes a frost-resistant and crack-resistant concrete structure, including a concrete body 1, a concrete base layer 2, a primary concrete layer 3 laid on top of the concrete base layer 2, an interface bonding layer 4 laid on top of the primary concrete layer 3, a secondary concrete layer 5 laid on top of the interface bonding layer 4, an anti-seepage reinforcement layer 6 laid on top of the secondary concrete layer 5, a waterproof layer 7 laid on top of the anti-seepage reinforcement layer 6, a crack-resistant reinforcement layer 8 laid on top of the waterproof layer 7, an elastic buffer layer 9 laid on top of the crack-resistant reinforcement layer 8, and a protective layer 10 laid on top of the elastic buffer layer 9. A steel mesh 11 is provided within the concrete base layer 2. The concrete base layer 2 provides stable support and ensures the structural integrity. Layer 3 enhances overall strength, improves impermeability and durability; interfacial bonding layer 4 strengthens interlayer bonding and prevents cracking; secondary concrete layer 5 absorbs and disperses external stress, reducing cracking; impermeability enhancement layer 6 resists external factors and reduces concrete damage; waterproof layer 7 keeps the structure's interior dry; crack-resistant enhancement layer 8 disperses and absorbs stress, improving stability; elastic buffer layer 9 improves flexibility and seismic performance; protective layer 10 prevents external environmental erosion and physical damage; and steel mesh 11 resists external loads and deformation. Through a multi-layered, multi-material combination design, comprehensive optimization of concrete performance is achieved. The close cooperation between each layer jointly improves the structure's frost resistance, crack resistance, and overall stability, providing strong protection for the safety and durability of building projects.

[0024] In some embodiments, both the primary concrete layer 3 and the secondary concrete layer 5 are made of high-performance concrete. High-performance concrete has low porosity and high density, which can effectively resist moisture penetration and freeze-thaw expansion.

[0025] In some embodiments, the interface bonding layer 4 is made of polymer-modified cement paste, and the impermeable reinforcement layer 6 is made of impermeable agent. The polymer-modified cement paste has strong adhesion and can form a good bond with the primary concrete layer 3 and the secondary concrete layer 5. The impermeable agent can further improve the impermeability of the concrete, prevent water from entering the interior of the concrete, and thus reduce the possibility of freezing damage.

[0026] In some embodiments, the waterproof layer 7 is made of polymer waterproof material, and the crack-resistant reinforcing layer 8 is made of fiber-reinforced material. The polymer waterproof material can resist the erosion of various natural environments and climatic conditions, such as ultraviolet rays and acid rain, to ensure a long-term stable waterproof effect. It also has good chemical stability and can resist the erosion of factors such as acid and alkali corrosion and oxidation, maintaining the integrity and functionality of the waterproof layer 7. The fiber-reinforced material can effectively prevent the generation and propagation of cracks and improve the overall crack resistance of the concrete structure.

[0027] In some embodiments, the elastic buffer layer 9 is made of rubber material and the protective layer 10 is made of polymer material. The rubber material has high elasticity and can effectively mitigate external impacts and vibrations. It can absorb and disperse vibration energy, thereby reducing damage to the concrete structure. The polymer material has high strength and high durability, which can effectively protect the concrete structure from external environmental erosion and help maintain the integrity and stability of the concrete structure.

[0028] In some embodiments, the reinforcing mesh 11 is made of high-quality stainless steel wire, which has excellent corrosion resistance and wear resistance.

[0029] Working principle or structural principle: During use, the concrete base layer 2 provides stable support for the upper concrete layer, ensuring the integrity of the structure. The primary concrete layer 3 is located on top of the concrete base layer 2, improving the impermeability and durability of the concrete. The main function of this layer is to enhance the overall strength of the structure and provide a stable base for subsequent layers. The interface bonding layer 4 effectively improves the bond strength between the primary concrete layer 3 and the secondary concrete layer 5, preventing cracks caused by insufficient interlayer bonding. The secondary concrete layer 5 absorbs and disperses external stress, reducing the generation and propagation of cracks. The impermeability enhancement layer 6 further enhances the impermeability of the concrete, preventing water from entering the concrete interior, thereby reducing freeze-thaw damage. The waterproof layer 7 provides additional... Waterproof protection ensures the structure remains internally dry during long-term use. Crack-resistant reinforcing layer 8 effectively disperses and absorbs external stress, reducing crack formation and improving overall structural stability. Elastic buffer layer 9 effectively absorbs and disperses external impacts and vibrations, improving structural flexibility and seismic performance. Protective layer 10 effectively prevents external environmental erosion and physical damage, protecting the internal structure from destruction. Reinforcing mesh 11 effectively resists external loads and deformations. This frost-resistant and crack-resistant concrete structure achieves comprehensive optimization of concrete performance through a multi-layered, multi-material combination design. The close cooperation between each layer enhances the structure's frost resistance, crack resistance, and overall stability, providing strong protection for the safety and durability of building projects.
