Cement base material of ultra-high performance concrete and preparation method of cement base material
The invention discloses an ultra-high performance concrete cement base material and a preparation method thereof, and the ultra-high performance concrete cement base material comprises the following components by weight: 450-550 parts of ordinary Portland cement, 120-200 parts of deionized water, 75-105 parts of silica fume, 170-210 parts of steel fiber, 10-18 parts of a water reducer, and 30-50 parts of solid powder. The water reducing agent is one or more of a polycarboxylic acid water reducing agent, a naphthalene water reducing agent and a modified sulfonate water reducing agent, and the components are added in a small amount and multiple times, so the problems that the regional concentration is too high due to the fact that the components are too concentrated, and residues are generated due to the fact that the components are difficult to completely react through stirring and mixing are solved; moreover, the added components are uniformly distributed on the surface of the mixture through the adding condition of circumferential oscillation equilateral dispersion, so the stirring difficulty is reduced, the added components are uniformly distributed on the mixture, and the problem of residues caused by higher regional component concentration and incomplete stirring and mixing is further avoided.
本发明公开了一种超高性能混凝土的水泥基材及其制备方法，按照重量份计包括如下组分：普通硅酸盐水泥450‑550份，去离子水120‑200份，硅灰75‑105份，钢纤维170‑210份，减水剂10‑18份，固体粉料30‑50份，所述减水剂为聚羧酸类减水剂、萘系减水剂和改性磺酸盐类减水剂的一种或几种，本发明在添加组分时通过少量多次的方式进行添加，避免了组分过于集中导致区域浓度过高以及难以通过搅拌混合完全反应而残留的问题，其次哦通过周向振荡等边分散的添加条件使得添加的组分较为均匀的分布在混合物的表面，降低了搅拌难度，且使得添加的组分均匀分布在混合物上，进一步避免了区域组分浓度较高以及未能完全搅拌混合而导致残留的问题。
