[0021] Various embodiments will be described below, and those skilled in the art should be able to easily understand the spirit and principles of the present invention by referring to the specific embodiments and the accompanying drawings. However, although some specific embodiments are described in detail herein, these embodiments are only exemplary and are not to be considered as limiting or exhaustive in any respect. Therefore, for those skilled in the art, various changes and modifications to the present invention should be obvious and easily achievable without departing from the spirit and principles of the present invention.

[0022] Figure 1 According to one embodiment of the present invention, a mixing material M1 and a preparation method thereof are proposed. The mixing material M1 can be used for surface construction operations of construction structures such as rough base coating or fine polishing. Specifically, the mixing material M1 may include a mixture 100. The mixture 100 is formed by mixing cement 10 and a first fine aggregate 15 in a weight ratio of 1:1 to 1:6. As mentioned above, the method for preparing the mixing material M1 includes mixing cement 10 and a first fine aggregate 15 in a weight ratio of 1:1 to 1:6 to form a mixture 100, and then selectively adding or not adding other materials 200 to the mixture 100 as the main body to form the mixing material M1.

[0023] Specifically, the first fine aggregate 15 can be a granular material formed by kneading clay as the main raw material, sintering and crushing. For example, clay can be kneaded into agglomerates as the main raw material, and then sintered at a high temperature below the melting temperature, and then crushed, cleaned, and sieved to form the first fine aggregate 15 with a desired particle size range. In addition, the agglomerates used for sintering can also contain shale, coal gangue and other materials in addition to clay. As mentioned above, the components of the granular material formed by sintering and crushing can at least include SiO2, Al2O3 and Fe2O3.

[0024] As mentioned above, according to some embodiments, among the SiO2, Al2O3 and Fe2O3 components of the granular material of the first fine aggregate 15, SiO2 may account for the largest proportion, followed by Al2O3, and Fe2O3 for the third. For example, in some embodiments, the percentage of SiO2 in the granular material of the first fine aggregate 15 may be about 45% or more, such as but not limited to 50% or 55%; the percentage of Al2O3 in the granular material of the first fine aggregate 15 may be about 10% or more, such as but not limited to 15% or 30%; and the percentage of Fe2O3 in the granular material of the first fine aggregate 15 may be about 5% or more, such as but not limited to 8% or 10%. In addition, in addition to the SiO2, Al2O3 and Fe2O3 components, the granular material of the first fine aggregate 15 may further include other components. For example, but not limited to MgO, CaO, etc.

[0025] According to some embodiments, the granular material of the first fine aggregate 15 may be irregular granular material with microscopic crystal phase arrangement of quartz, albite, chlorite, hematite, etc. However, this is only an example, and the crystal phase or structural arrangement of the first fine aggregate 15 of other embodiments of the present invention is not limited thereto.

[0026] According to some embodiments, the first fine aggregate 15 can be red bricks and concrete blocks from the remaining earth and stone in the construction, which are recycled and crushed. For example, it can be the remaining or cleared construction materials during new construction, demolition, or reconstruction, which are recycled and crushed. That is, according to some embodiments of the present invention, these resources can be used to make the mixing material M1, and the remaining earth and stone from the construction can be used again for painting or decoration of various structures. Therefore, the resource recovery of the remaining earth and stone from the construction can be improved, environmental protection and circular economy can be promoted, the development and consumption of natural resources can be reduced, and the cost of materials used in painting or decoration operations such as rough embryo priming or fine embryo powder finishing can be reduced. In addition, by recycling and reusing the remaining earth and stone from the construction, the generation of waste can be greatly reduced, and the space, energy, resources and manpower required for processing waste can be reduced or avoided.

[0027] As mentioned above, the granular material of the first fine aggregate 15 may include components of construction waste earth and stone such as red bricks, and at least include components such as SiO2, Al2O3 and Fe2O3. However, recycling and reusing construction waste earth and stone is only an example, and other embodiments of the present invention are not limited thereto. For example, the first fine aggregate 15 may also be a granular material obtained by kneading, sintering and crushing clay as the main raw material specifically for preparing the mixing material M1, and at least includes components SiO2, Al2O3 and Fe2O3, and is not necessarily red bricks and / or concrete blocks from construction waste earth and stone. In addition, according to some embodiments, the granular material obtained by kneading, sintering and crushing clay as the main raw material is not limited to materials with the same or similar components as red bricks and / or concrete blocks. As mentioned above, depending on the components of other auxiliary raw materials added to clay as the main raw material and the components of clay as the main raw material, the components of the granular material obtained by kneading, sintering and crushing may be partially different. As mentioned above, the differences should be within the permissible deviation range that can be understood by those skilled in the art, and materials with differences but meeting the defined properties of the present invention should fall within the category of the granular materials of the first fine aggregate 15 of each embodiment of the present invention.

[0028] In addition, according to some embodiments, due to the Fe2O3 component, the granular material of the first fine aggregate 15 may be red in whole or in part. However, the present invention is not limited thereto, and under the Fe2O3 component, the granular material of the first fine aggregate 15 may also be other colors other than red according to other components.

[0029] According to some embodiments, the granular material produced as described above may have a porosity and water absorption rate exceeding 5%. As mentioned above, general natural stone or sand may have a water absorption rate of 1% to 2%, but the granular material according to each embodiment of the present invention may have a porosity and water absorption rate exceeding 5% or even more than 10%, which is significantly higher than the porosity and water absorption rate of general natural stone or sand. For example, the granular material of the first fine aggregate 15 may have a water absorption rate of 8%, but is not limited to this. For example, the granular material of the first fine aggregate 15 may also have a water absorption rate of up to 15%. In addition, the granular material produced as described above may have a specific gravity between 1.6 and 2.5.

[0030] As mentioned above, since the granular material of the first fine aggregate 15 has a high porosity and water absorption rate, it has a better water retention rate, which can reduce the cracking probability caused by factors such as shrinkage due to water loss. When applying rough roughing and / or fine roughing, the porosity and water absorption rate of the surface coating of the finished base layer or polishing layer can be increased. Therefore, the air permeability, water permeability and drainage of the completed structure can be improved, and the defects of the surface coating of the construction structure can be reduced or avoided. For example, but not limited to water seepage, or micro cracks.

[0031] In addition, in some embodiments, the first fine aggregate 15 of granular material made of clay as the main raw material, which is kneaded, sintered and crushed, may have alkaline properties, thereby avoiding the acidic properties from corrosive to the building structure or other materials such as steel bars, thereby improving the life, earthquake resistance and reliability of the finished engineering product.

[0032] According to some embodiments, the granular material prepared as described above, when used as the first fine aggregate 15 for preparing the mixed material M1, may have a particle size between 75 μm and 3 mm. As above, in order to prepare the mixed material M1, the granular material of the first fine aggregate 15 may preferably be mixed with the cement 10 with a particle size between 75 μm and 3 mm. However, other embodiments according to the present invention are not limited thereto. For example, the granular material of the first fine aggregate 15 that can be used for rough base or fine powdering may also be mixed with the cement 10 with a particle size lower than 75 μm or even lower than 62.5 μm. As above, according to the present embodiment, the granular material used as the first fine aggregate 15 does not have the properties of mud, and therefore a smaller particle size may be used to mix into the mixed material M1, thereby controlling and reducing the mud content of the mixed material M1. Thus, material defects caused by mud in the mixed material M1 can be reduced or avoided, such as uneven distribution of materials in the mixed material M1 due to easy aggregation of mud, or increased water demand due to adsorption of chemical admixtures by mud. As described above, according to some embodiments of the present invention, the mixed material M1 thus prepared can reduce defects such as easy cracking of the surface coating of the mixed material M1 by reducing the mud content.

[0033] In addition, conventional cement and water will produce cementation when mixed alone. However, the granular material of the first fine aggregate 15 according to each embodiment of the present invention will not produce cementation when mixed alone with water. Specifically, the granular material of the first fine aggregate 15 according to each embodiment of the present invention will not produce a significant volume change when mixed alone with water, the interface between individual particles will not be significantly reduced, and the particles will not be connected or fused with each other.

[0034] Furthermore, the granular materials of the first fine aggregate 15 according to each embodiment of the present invention are also difficult or impossible to form balls when mixed with water alone. In detail, the general existing river sand or sea sand is easy to be rolled into sand balls or mud balls when mixed with a small amount of water, but the granular materials of the first fine aggregate 15 according to each embodiment of the present invention are more difficult to be close to each other by various effects such as but not limited to hydrogen bonds or van der Waals forces generated by water as a medium than the general existing river sand or sea sand. Therefore, even if mixed with a small amount of water, the granular materials of the first fine aggregate 15 according to each embodiment of the present invention cannot or are difficult to be rolled into and maintain agglomerates with a fixed shape or volume. Therefore, compared with general river sand or sea sand, this property of the first fine aggregate 15 can improve the uniformity of material distribution when mixed to form the mixed material M1, thereby improving the stability of the physicochemical properties of the mixed material M1, the consistency of the composition ratio, and the overall strength and reliability of the coating completed based on it.

[0035] In addition, the mixed material M1 is a material mainly composed of a mixture 100 of cement 10 and first fine aggregate 15. Figure 1 As shown, in addition to cement 10 and the first fine aggregate 15, the mixed material M1 may further selectively add or not add other materials 200. For example, a trace material that helps waterproofing may be added, and a trace material that helps to present the desired color may be added. Alternatively, other traditional fine aggregates other than the first fine aggregate 15 may be added. Alternatively, any additives or materials that may be used in traditional existing construction projects or mud works may be added. As mentioned above, except for the proportion of water, when the proportion of the mixture 100 is the highest as the main body (50% to 100%), the mixed material M1 may arbitrarily add a small amount of other construction or mud work materials according to the needs of the intended construction project. As mentioned above, this is clear to those skilled in the art and will not be repeated here.

[0036] According to some embodiments, the mixed material M1 may further include water. For example, the material 200 may include water. In detail, before the rough base coating or fine base polishing coating is applied, the mixed material M1 may be a mixture 100 mixed with water based on a preset water-cement ratio of 0.42 to 0.8. Thus, the mixed material M1 may have fluidity, or the whole mixed material M1 may have cementitious properties through the reaction between cement 10 and water.

[0037] As above, Figure 2 and Figure 3 As shown, based on the cementitiousness and / or fluidity of the mixed material M1 after adding water, the mixed material M1 can be used to apply the surface of the structure 25 or 35, and the corresponding coating application operations such as painting or decoration can be performed. As mentioned above, after the mixed material M1 is applied to the structure 25 or 35 and left to stand for a period of time, a hardened desired coating can be formed. For example, Figure 2 The rough base layer 250 shown, or Figure 3 The fine powder layer 350 is shown. However, the mixing material M1 of other embodiments of the present invention can be applied in a manner not limited thereto. For example, the mixing material M1 according to each embodiment can be used as a surface finishing material, a surface leveling material or a surface protection material for various structures.

[0038] As mentioned above, Figure 4 is a schematic diagram of the result of actually using the mixing material prepared for rough base coating to perform rough base coating according to an embodiment of the present invention, and Figure 5 It is a schematic diagram of the result of fine grain polishing actually performed using the mixing materials formulated for fine grain polishing according to an embodiment of the present invention.

[0039] According to some embodiments, the coating formed by using the mixing material M1 may have a thickness between 1 cm and 6 cm. For example, a thickness between 1.5 cm and 5 cm. However, this is only an example, and the present invention is not limited thereto. For example, according to some embodiments, the coating formed by using the mixing material M1 may actually have a thickness between 2 cm and 3 cm when applied.

[0040] In addition, according to some embodiments, the ratio of cement 10 to the first fine aggregate 15 in the mixed material M1 may be changed accordingly depending on the conditions of rough priming or fine polishing.

[0041] As described above, according to one embodiment, in the case of applying rough-brick primer, in the mixing material M1, the mixture 100 can be formed by mixing cement 10 and the first fine aggregate 15 in a ratio of 1:3 to 1:5. For example, in the case of applying rough-brick primer, the mixture 100 can be formed by mixing cement 10 and the first fine aggregate 15 in a ratio of 1:5. As described above, when the proportion of the first fine aggregate 15 is higher, the use and consumption of cement 10 can be reduced, thereby reducing the resources and costs required to use cement 10.

[0042] In contrast, according to one embodiment, in the case of applying fine grain milling, in the mixing material M1, the mixture 100 may be formed by mixing cement 10 and the first fine aggregate 15 in a ratio of 1:2 to 1:4. For example, in the case of applying fine grain milling, the mixture 100 may be formed by mixing cement 10 and the first fine aggregate 15 in a ratio of 1:3. As mentioned above, when the proportion of the first fine aggregate 15 is higher, the use and consumption of cement 10 can be reduced, thereby reducing the resources and costs required to use cement 10.

[0043] In addition, according to some embodiments, the particle size range of the granular material of the first fine aggregate 15 used in the mixing material M1 applied to the fine roughing can be smaller than the particle size range of the granular material of the first fine aggregate 15 used in the mixing material M1 applied to the rough roughing. For example, according to some embodiments, the average particle size of the granular material of the first fine aggregate 15 used in the mixing material M1 applied to the fine roughing can be smaller than the average particle size of the granular material of the first fine aggregate 15 used in the mixing material M1 applied to the rough roughing.

[0044] According to some embodiments, when the granular material of the first fine aggregate 15 used in the mixing material M1 according to the present invention has a fineness modulus of less than 1.5 or at least 1.5, it can still be applied to the structure when mixed with water and cement 10 to form a corresponding surface coating. Compared with mud and sand materials with the same fineness modulus, the defects of coating bulge or convexity, or even shedding, can be reduced or avoided.

[0045] As mentioned above, by performing coating operations such as painting or decoration using the mixed material M1 according to various embodiments of the present invention, a surface coating having sufficient strength, reliability and expected appearance can be established.

[0046] In summary, the mixing materials and methods for preparing the mixing materials according to the various embodiments of the present invention can be applied to coating operations such as painting and finishing of structures. Continuing from the above, according to the various embodiments of the present invention, other resources and raw materials other than existing materials can be used to prepare or mix the mixing materials. In this way, the applicability of different resources and raw materials can be developed, the recycling of residual earth and stone from construction can be improved, and the consumption of materials or natural resources that are commonly used in construction projects or mud works and are even scarce can be reduced. Therefore, the mixing materials and methods for preparing the mixing materials according to the various embodiments of the present invention can improve the utilization and selectivity of various materials or resources while maintaining and / or improving the quality of the finished products of painting and finishing of the surface of the structure, and reduce the consumption rate of existing conventional materials or resources.

[0047] The above descriptions are only some preferred embodiments of the present invention. It should be noted that the present invention may be subjected to various changes and modifications without departing from the spirit and principles of the present invention. It should be understood by those skilled in the art that the present invention is defined by the scope of protection claimed in the application documents, and that various possible substitutions, combinations, modifications and diversions, etc., in accordance with the intent of the present invention, do not exceed the scope of the present invention defined by the scope of protection claimed in the application documents.
