Steam-curing-free low-cost ultra-high performance concrete and preparation method thereof
The invention discloses steam-curing-free low-cost ultra-high performance concrete and a preparation method thereof, relates to the technical field of building materials, and solves the problems of high cost and cumbersome curing of ultra-high performance concrete in the prior art. The steam-curing-free low-cost ultra-high performance concrete is prepared from the following raw materials in parts by weight: 40-55 parts of ordinary Portland cement; 5 to 20 parts of rapid hardening sulphoaluminate cement; 0-15 parts of mineral powder; 5 to 20 parts of silica fume; 15 to 25 parts of fly ash; 5-20 parts of limestone powder; 80 to 125 parts of machine-made sand; 12-18 parts of waste steel fiber; 1-2 parts of a water reducing agent; and 17-20 parts of water. The preparation method of the steam-curing-free low-cost ultra-high performance concrete comprises the following steps: weighing the raw materials in parts by weight; after the raw materials are uniformly mixed, the steam-curing-free low-cost ultra-high performance concrete is obtained. The steam-curing-free low-cost ultra-high performance concrete is low in cost, simple and convenient to produce and excellent in various properties.
本发明公开了一种免蒸养低成本超高性能混凝土及其制备方法，涉及建筑材料技术领域，解决现有技术中超高性能混凝土成本高，养护繁琐的问题。本发明的免蒸养低成本超高性能混凝土由包括以下按重量份的原料制成：普通硅酸盐水泥40～55份；快硬硫铝酸盐水泥5～20份；矿粉0～15份；硅灰5～20份；粉煤灰15～25份；石灰石粉5～20份；机制砂80～125份；废旧钢纤维12～18份；减水剂1～2份；水17～20份。本发明的免蒸养低成本超高性能混凝土的制备方法包括：按重量份称取各原料；将原料混合均匀后，即得所述免蒸养低成本超高性能混凝土。本发明的免蒸养低成本超高性能混凝土成本低廉，生产简便，各项性能优良。
