High-strength prefabricated building material and preparation method thereof
The invention discloses a high-strength prefabricated building material and a preparation method thereof, and relates to the technical field of concrete. The high-strength prefabricated building material is prepared from the following raw materials: 80 to 160 parts of cement, 10 to 40 parts of silicate clay, 260 to 400 parts of gravel, 180 to 360 parts of sand, 120 to 260 parts of fly ash, 8 to 30 parts of fiber-loaded carbon nanotubes, 3 to 19 parts of an accelerator, 4 to 20 parts of a water reducing agent and 32 to 64 parts of water. The fiber-loaded carbon nanotube mainly comprises a composite fiber and a modified carbon nanotube, wherein the weight ratio of the composite fiber to the modified carbon nanotube is 1: (0.4-0.6); the preparation method of the prefabricated building material comprises the following steps: S1, mixing cement, silicate clay, gravel, sand, fly ash, fiber-loaded carbon nanotubes, an accelerator, a water reducing agent and water, and uniformly stirring to obtain concrete; s2, concrete is poured into a prefabricated building material mold, vibrated uniformly and naturally air-dried until the concrete is solidified; and S3, after low-temperature baking is conducted on the cured mold, cooling and demolding are conducted, and the prefabricated building material is obtained. The prefabricated building material provided by the invention has relatively high mechanical strength.
本申请公开了一种高强预制建筑材料及其制备方法，涉及混凝土技术领域。一种高强预制建筑材料原料包括：80‑160份水泥、10‑40份硅酸盐黏土、260‑400份碎石、180‑360份砂、120‑260份粉煤灰、8‑30份纤维负载碳纳米管、3‑19份速凝剂、4‑20份减水剂、32‑64份水；所述纤维负载碳纳米管主要包括复合纤维和改性碳纳米管，二者重量比为1：（0.4‑0.6）；所述预制建筑材料的制备方法如下：S1.将水泥、硅酸盐黏土、碎石、砂、粉煤灰、纤维负载碳纳米管、速凝剂、减水剂、水混合，搅拌均匀得到混凝土；S2.将混凝土浇筑于预制建筑材料模具中，振动均匀，自然风干至混凝土固化；S3.将固化的后模具进行低温烘烤后，冷却，脱模，得到预制建筑材料。本申请提供的预制建筑材料具有较高的力学强度。
