Ultra-high performance concrete with high titanium slag as coarse aggregate and preparation method of ultra-high performance concrete
The invention discloses ultra-high performance concrete taking high titanium slag as coarse aggregate and a preparation method of the ultra-high performance concrete. The ultra-high performance concrete comprises 436-489kg/m < 3 > of cement, 73-82kg/m < 3 > of silica fume, 218-245kg/m < 3 > of fly ash, 949-983kg/m < 3 > of coarse aggregate, 659-683kg/m < 3 > of fine aggregate, 172-198kg/m < 3 > of water, steel fibers accounting for 1.5% of the total volume of the raw materials and a water reducer accounting for 1% of the total weight of the raw materials. The invention has excellent mechanical properties, durability and volume stability, the preparation method is simple and convenient to operate, the disposal rate and the use value of the slag are also improved, and the cost is saved.
本发明公开了一种高钛矿渣作粗骨料的超高性能混凝土及其制备方法，所述超高性能混凝土包括每立方米混凝土计的436～489kg/m3水泥、73～82kg/m3硅灰、218～245kg/m3粉煤灰、949～983kg/m3粗骨料、659～683kg/m3细骨料、172～198kg/m3水，以及占以上原料总体积百分比1.5％的钢纤维和以上原料总重量百分比1％的减水剂。本发明具有优异的力学性能、耐久性能和体积稳定性，制备方法简单，操作方便，还提升了矿渣的处置率和使用价值，节省了成本。
