Hybrid steel fiber ultra-high performance concrete and preparation method thereof
The invention discloses mixed steel fiber ultra-high performance concrete and a preparation method thereof. The concrete is prepared from the following components in parts by mass: 700 parts of quartz sand, 300 parts of quartz powder, 230 parts of silica fume, 770 parts of cement, 156 parts of steel fibers, 35 parts of a high-efficiency water reducing agent and 135.5 parts of water. The particle size range of the quartz sand is 394.2 to 1019.5 mu m; the particle size range of the quartz powder is 152.5 to 229.1 [mu] m; the average particle size of the silica fume is 0.2 mu m, and the content of SiO2 is 98%. According to the method, the toughening indexes of steel fibers with different volume mixing amounts can be determined according to the performance parameters of different types of steel fibers; and the optimal toughening effect is achieved by reasonably matching the steel fibers with different mixing amounts.
本发明公开了一种混杂钢纤维超高性能混凝土及其制备方法，该混凝土包括以质量份数计的以下组分：石英砂700份，石英粉300份，硅灰230份，水泥770份，钢纤维156份，高效减水剂35份和水135.5份；石英砂粒度区间为394.2‑1019.5μm；石英粉粒度区间为152.5‑229.1μm；硅灰平均粒径为0.2μm，SiO2含量为98％。本发明可根据不同种类钢纤维性能参数，可以确定不同体积掺量钢纤维增韧指数；通过合理搭配不同掺量钢纤维使其达到最优化的增韧效果。
