Thermal-insulation ductile cement-based material and preparation method thereof
The thermal-insulation ductile cement-based material disclosed by the invention is prepared from the following raw materials in parts by weight: 45 to 55 parts of cement, 45 to 55 parts of fly ash, 35 to 50 parts of river sand, 0.43 to 1.29 parts of aerogel, 0.8 to 1.2 parts of a water reducing agent, 0.3 to 0.8 part of a silane coupling agent, 26 to 30 parts of water and 2.30 to 2.40 parts of synthetic fibers, the total weight part of the cement and the fly ash is 100 parts. The preparation method of the material comprises the following process steps: (1) sequentially putting the aerogel powder, the fly ash, the cement and the river sand into an opened stirrer, and uniformly mixing to obtain a mixed dry material; (2) dissolving a silane coupling agent in water, and uniformly mixing to obtain a silane coupling agent solution; (3) adding a silane coupling agent solution into the mixed dry material, and uniformly mixing to obtain first slurry; (4) adding a water reducing agent into the first slurry, and uniformly mixing to obtain second slurry; (5) adding synthetic fibers into the second slurry, and uniformly mixing to obtain third slurry; and (6) carrying out injection molding on the third slurry, demolding and curing.
本发明所述保温延性水泥基材料，由以下重量份的原料制备而成：水泥45～55份，粉煤灰45～55份，河砂35～50份，气凝胶0.43～1.29份，减水剂0.8～1.2份，硅烷偶联剂0.3～0.8份，水26～30份，合成纤维为2.30～2.40份；对于水泥和粉煤灰，它们的总重量份还应为100份。上述材料的制备方法，工艺步骤为：(1)依次将气凝胶粉末、粉煤灰、水泥和河砂放入开启的搅拌机中混合均匀得到混合干料；(2)将硅烷偶联剂溶于水中并混合均匀得到硅烷偶联剂溶液；(3)将硅烷偶联剂溶液加入混合干料中并混合均匀，得到第一浆体；(4)将减水剂加入第一浆体中并混合均匀得到第二浆体；(5)将合成纤维加入第二浆体中并混合均匀得到第三浆体；(6)将第三浆体注模成型，再经脱模、养护即可。
