[0036] Step 300, pouring the prepared casting raw material into the mold, and vibrating the mold at the same time, so that the mold can be poured with materials in a vibrating state.

[0037] Step 400, after pouring, the mold is evacuated to discharge the bubbles in the poured structure.

[0038] Step 500, curing and demoulding. Step 500 includes:

[0039] Send the mold as a whole to the steam curing room for steam curing for more than 12 hours at a temperature not lower than 80 degrees;

[0040] Lower the temperature in the steaming room so that the temperature difference between the steaming room and the outside of the growth room is less than 20℃;

[0041] Demolding the components;

[0042] Steam the components again for no less than 48 hours at a temperature no lower than 90 degrees;

[0043] The components are cooled down gradually; when the component temperature is no higher than the ambient temperature by 20°C, the components are placed in a natural environment for curing, and eventually the component temperature is consistent with the ambient temperature.

[0044] In this application, the SD IC dry powder includes white silicate cement, white silica fume, 325 mesh quartz powder, quartz sand, kaolin, nano-CaO, nano-Na2O, calcium carbonate, and titanium dioxide. More specifically, the raw materials and their corresponding mass parts are as follows:

[0045] White Portland cement: 1.0;

[0046] White silica fume: 0.1-0.5;

[0047] 325 mesh quartz powder: 0.2-0.5;

[0048] Quartz sand: 0.6-1.5;

[0049] Kaolin: 0.05-0.18;

[0050] Nano-CaO: 0.02-0.08;

[0052] Calcium carbonate: 0.02-0.06;

[0053] Titanium dioxide: 0.003-0.12.

[0054] In step 100, the casting raw material is mixed with composite material, water, admixture, fiber, and basic coloring agent. Specifically, step 100 includes: step 101-step 104.

[0055] Step 101, using one or more basic colorants to prepare a colorant of a desired color, and mixing the prepared colorant with water, and stirring evenly to form colorant water;

[0056] Step 102, mixing the SDI C dry powder and the colorant water in proportion, and stirring for more than 15 minutes to mix the materials evenly;

[0057] Step 103, adding an additive to the uniformly stirred material, and then continuing to stir for more than 5 minutes to uniformly stir the material;

[0058] Step 104, continue to add fibers, and then continue stirring for more than 10 minutes to stir the materials evenly and achieve self-fluidization.

[0059] Specifically, in step S101, the type of basic colorant required, the ratio of the basic colorant and the amount of the basic colorant are determined according to the color required by the design, and the ratio of the required colorant to water is determined. In addition, if there are two or more colors of the component, separate calculations and proportions are required. The basic colorants of different colors determined in the above steps are mixed evenly to form a colorant of the required color. Finally, water and the adjusted colorant are mixed evenly according to the set ratio to form the colorant water required later. In addition, it should be noted that when configuring a colorant of one color, a basic colorant of one color or multiple basic colorants of different colors can be used for configuration.

[0060] In step 102, first, SDIC dry powder and colorant water are mixed evenly according to proportion. In step 103, admixtures are added continuously and mixed evenly. In step 104, fibers are added continuously and mixed evenly. Fibers are used to increase strength and toughness and prevent cracks from appearing on the outer surface of components. In a specific embodiment, the fibers are polypropylene fibers. Thus, a self-fluidizing casting raw material is obtained through steps 101 to 104.

[0061] In step 200, the mold is prepared: the mold joint surface is cleaned, mold release oil is evenly applied on the mold joint surface, and the mold is combined to form a casting space. In this step, the role of the mold release oil is to solve the normal separation of the casting structure and the mold after casting, so as to ensure the quality of the casting structure surface. Further, in step 200, before the mold is combined, it also includes: according to the design of the finished casting structure, prefabricated steel bars or meshes, corrugated pipes and other structural reinforcement components and / or pre-embedded connection embedded components connected to other components are arranged inside the mold combination space.

[0062] In step 300, the casting material prepared in step 100 is cast into the mold, and the mold is vibrated at the same time, so that the mold is cast in a vibrating state. Further, in step 300, during casting, casting is performed in the mold at the same position, and the casting material fills the casting space of the mold in a self-flowing manner in the mold, and in step 300, the casting is continuous and the casting time does not exceed 30 minutes.

[0063] In one embodiment of the present application, the construction method further includes: coding and packaging the components.

[0064] In step 400, after pouring, the mold is evacuated to form a negative pressure inside the mold relative to the space outside the mold after pouring. The main function of this step is to discharge the bubbles in the structure formed after pouring to improve the flatness, smoothness, consistency and other decorative effects of the outer surface of the structure.

[0065] In step 500, the curing and demoulding include: sending the mold as a whole to a steam curing room for steam curing for more than 12 hours at a temperature not lower than 80 degrees; lowering the temperature in the steam curing room so that the temperature difference between the inside of the steam curing room and the outside of the curing room is less than 20 degrees; demoulding the component; steam curing the component again for not less than 48 hours at a temperature not lower than 90 degrees; cooling the component, gradually cooling it; when the temperature of the component is not higher than the ambient temperature by 20 degrees, placing the component in a natural environment for curing in the natural environment, and finally the temperature of the component is consistent with the ambient temperature.

[0066] In one embodiment of the present application, if there are two or more colors of the component, separate calculations and proportions are required. Based on the design of multiple colors, in step 100, a plurality of different colors of colorants are respectively configured using a basic colorant, and the configured colorants of the plurality of different colors are respectively mixed with water and stirred evenly to form a plurality of groups of colorant waters of different colors; based on the plurality of groups of colorant waters of different colors, a plurality of groups of casting raw materials of different colors are respectively prepared according to the proportions; in step 300, the plurality of groups of casting raw materials of different colors are separately cast.

[0067] When the component has two or more colors, step 100 specifically includes:

[0068] Using the basic colorant to prepare a plurality of different colored colorants, respectively, and mixing the prepared colorants of the plurality of different colors with water respectively, and stirring evenly to form a plurality of groups of colorant waters of different colors;

[0069] Mixing a plurality of different colored colorant waters with the SDI C dry powder in proportion to obtain a plurality of mixed materials corresponding to different colors, and stirring the plurality of mixed materials for more than 15 minutes to uniformly stir the plurality of mixed materials;

[0070] Add additives to multiple groups of mixed materials respectively, and then continue stirring for more than 5 minutes to stir the multiple groups of mixed materials evenly;

[0071] Continue to add fibers to the multiple groups of mixed materials, and then continue to stir for more than 10 minutes to stir the multiple groups of mixed materials evenly and achieve self-fluidization.

[0072] In step 300, multiple groups of casting materials of different colors are cast separately, and finally multiple colors are formed on the structural components.

[0073] In one embodiment of the present application, when a component is composed of only one color, based on the design of one color, in step 100, a colorant of one color is configured using a basic colorant, and the configured colorant of one color is mixed with water and stirred evenly to form a colorant water of one color; then, based on the colorant water of one color, a casting material of one color is prepared according to the ratio; in step 300, the casting material of one color is cast.

[0074] Step 100 specifically includes:

[0075] Using one or more basic colorants to prepare a colorant of a desired color, and mixing the prepared colorant with water, and stirring evenly to form a colorant water;

[0076] The colorant water obtained in the previous part and the SDI C dry powder are mixed in proportion to obtain a mixture, and stirred for more than 15 minutes to stir the mixture uniformly;

[0077] Add the admixture to the well-mixed material, and then continue to stir for more than 5 minutes to make the mixture well-mixed;

[0078] Continue adding the fibers and continue stirring for 10 minutes more to homogenize the mixture and make it self-fluidizing.

[0079] In step 300, casting materials of one color are cast separately, and finally a single color is formed on the structural member.
