High-strength cement-based composite material and preparation method thereof
The invention provides a high-strength cement-based composite material and a preparation method thereof.The preparation method comprises the steps that S1, electroplating sludge and building residue soil are prepared, mixed and sintered, pottery sand is obtained, and the pottery sand comprises SiO2, Al2O3 and Fe2O3; s2, Portland cement, silica fume and blast furnace slag are mixed and stirred, and a mixed material is obtained; adding river sand into the mixed material, and further stirring; s3, pre-wetted pottery sand, a water reducing agent and part of water are added into the mixed material stirred in the step S2, and stirring continues; and S4, adding the residual water into the mixed material, and stirring to obtain the high-strength cement-based composite material. The invention also provides components and a ratio of the composite material. According to the invention, the problem of shrinkage of a high-strength cement matrix along with strength improvement in the prior art is solved, the problems of cracking and shortened service life of the shrunk concrete matrix are solved, and the high-strength cement matrix has relatively high commercial value and popularization value.
本发明提供了一种高强水泥基复合材料及其制备方法，制备方法包括：S1：准备电镀污泥与建筑渣土并混合并烧结，得到陶砂，所述陶砂的成分包括SiO2、Al2O3、Fe2O3；S2：将硅酸盐水泥、硅灰和高炉矿渣进行混合并搅拌得到混合物料；加入河砂至所述混合物料中进一步进行搅拌；S3：加入预湿处理后的陶砂、减水剂以及部分水至所述步骤S2搅拌后的混合物料中，继续搅拌；S4：加入剩余的水至所述混合物料中，搅拌后得到高强水泥基复合材料。本发明还提供了该复合材料的组分及其配比。通过本发明克服了现有技术中高强水泥基体随着强度提高而造成的收缩问题，以及收缩后混凝土基体出现的开裂、寿命降低的问题，具备较高的商业化价值与推广价值。
