Ultra-high performance concrete and preparation method thereof
The invention discloses ultra-high performance concrete and a preparation method thereof. The ultra-high performance concrete is prepared from the following components in parts by mass: 690 to 850 parts of cement, 200 parts of silica fume, 226 to 348 parts of quartz sand of 40 to 70 meshes, 464 to 556 parts of quartz sand of 26 to 40 meshes, 340 to 348 parts of quartz sand of 16 to 26 meshes, 158 to 200 parts of steel fiber, 22.22 to 34.65 parts of water reducing agent and 168 to 182 parts of water. According to the invention, the problems of high production cost and complex production process of the ultra-high performance concrete are solved.
本发明公开了一种超高性能混凝土及其制备方法，包括：690～850质量份的水泥、200质量份的硅灰、226～348质量份的40～70目石英砂、464～556质量份的26～40目石英砂、340～348质量份的16～26目石英砂、158～200质量份的钢纤维、22.22～34.65质量份的减水剂以及168～182质量份的水。本发明解决了超高性能混凝土的生产成本高强且生产工艺复杂的问题。
