Machine-made sand and aeolian sand co-doped ultra-high performance concrete and preparation method thereof
The invention relates to machine-made sand and aeolian sand co-doped ultra-high performance concrete and a preparation method thereof. The content per cube of the machine-made sand and aeolian sand co-doped ultra-high performance concrete comprises: 650 to 850 kg/m<3> of cement, 300 to 450 kg/m<3> of a mineral admixture, 600 to 800 kg/m<3> of machine-made sand, 200 to 400 kg/m<3> of aeolian sand,78 to 220 kg/m<3> of steel fiber, 11.2 to 14.2 kg/m<3> of a water reducing agent and 185 to 210 kg/m<3> of water. The machine-made sand and the aeolian sand are adopted to replace natural river sand,the prepared machine-made sand and aeolian sand co-doped ultra-high performance concrete has good working performance, mechanical performance and durability, the problem of shortage of natural river sand resources is solved, local resources are reasonably utilized, and the production cost is reduced.
本申请涉及一种机制砂与风积沙复掺的超高性能混凝土及其制备方法，机制砂与风积沙复掺的超高性能混凝土单方用量包括：水泥650‑850kg/m，矿物掺合料300‑450kg/m，机制砂600‑800kg/m，风积沙200‑400kg/m，钢纤维78‑220kg/m，减水剂11.2‑14.2kg/m，水185‑210kg/m。本发明采用机制砂和风积沙代替天然河砂，制备的机制砂与风积沙复掺的超高性能混凝土具有良好的工作性能、力学性能和耐久性能，既解决了天然河砂资源紧缺的问题，又合理的利用了当地资源，降低了生产成本。
