C80 high-strength high-performance machine-made sand concrete and preparation method thereof
The invention relates to C80 high-strength and high-performance machine-made sand concrete and a preparation method thereof. The concrete is prepared from the following raw materials in parts by weight: 410 to 464 parts of cement, 43 to 94 parts of superfine composite powder, 44 to 100 parts of slag powder, 20 to 32 parts of semi-dense silica fume, 155 parts of water, 571 to 582 parts of machine-made sand, 1032 to 1111 parts of coarse aggregate and 11.6 to 13 parts of water reducing agent. By reducing the water-binder ratio, carefully selecting the cement variety, screening the high-quality aggregate, adding the mineral admixture and the chemical additive and adopting the specific preparation method, the cement is prepared. Therefore, the C80 high-strength high-performance machine-made sand concrete with excellent workability, pumping performance, compressive strength, impermeability, freeze-thaw cycle resistance and durability is provided, technical benefits are brought to engineering structure materials, and huge social and economic benefits and environmental protection benefits can be generated.
本发明涉及一种C80高强高性能机制砂混凝土及其制备方法，所述的混凝土包括如下原料：水泥410‑464重量份、超细复合粉43‑94重量份、矿渣粉44‑100重量份、半加密硅灰20‑32重量份、水155重量份、机制砂571‑582重量份、粗骨料1032‑1111重量份、减水剂11.6‑13重量份。本发明通过降低水胶比、慎重选择水泥品种、筛选高质量集料、加入矿物掺合料、化学添加剂以及采用特定的制备方法，进而提供了一种具有优异的和易性、泵送性能、抗压强度、抗渗性能、抗冻融循环性能以及耐久性能的C80高强高性能机制砂混凝土，不仅为工程结构材料带来技术效益，还能产生巨大的社会经济效益和环境保护效益。
