High-slump ultrahigh-strength high-performance concrete and preparation method thereof
The invention discloses a high-slump ultrahigh-strength high-performance concrete and a preparation method thereof. The ultrahigh-strength high-performance concrete comprises the following components:100-200 parts of water, 400-600 parts of cement, 80-135 parts of fly ash, 50-100 parts of silica fume, 0-100 parts of fiber, 10-20 parts of a water reducer, 600-700 parts of sand and 800-1000 parts of broken stone. By adopting the large-slump ultrahigh-strength high-performance concrete and the preparation method thereof, the prepared ultrahigh-strength high-performance concrete has the advantages of being good in working performance, small in use amount of cementing materials, good in volume stability, high in elasticity modulus, good in shrinkage and creep resistance and low in cost. Therefore, the problems of obvious shrinkage, high manufacturing cost and the like caused by high consumption of the traditional UHPC cementing material are solved.
本发明公开了一种大坍落度的超高强高性能混凝土及其制备方法，该超高强高性能混凝土，包括如下组分：水100‑200份、水泥400‑600份、粉煤灰80‑135份、硅灰50‑100份、纤维0‑100份、减水剂10‑20份、砂子600‑700份、碎石800‑1000份。采用本申请的大坍落度的超高强高性能混凝土及其制备方法，制备的超高强高性能混凝土具有工作性能好、胶凝材料用量少、体积稳定性佳、弹性模量高、抗收缩和徐变性能佳、成本低廉的优点。解决了传统UHPC胶凝材料用量大所导致的收缩明显、造价高昂等问题。
