Machine-made sand self-compacting rock-fill concrete material and preparation method thereof
The invention discloses a machine-made sand self-compacting rock-fill concrete material which comprises the following components in percentage by volume: 50-55% of rock-fill body and 45-50% of machine-made sand self-compacting concrete. The machine-made sand self-compacting rock-fill concrete material comprises the following components in proportion: 530-560 kg/m < 3 > of cement, 85-105 kg/m < 3 > of mineral powder, 70-90 kg/m < 3 > of fly ash, 55-65 kg/m < 3 > of silica fume, 690-720 kg/m < 3 > of sand, 850-900 kg/m < 3 > of gravel, 16.25-16.78 kg/m < 3 > of an additive and 140-160 kg/m < 3 > of water. The prepared machine-made sand self-compacting rock-fill concrete material has good working performance and mechanical performance, the price of machine-made sand is lower than that of natural sand, and the engineering cost can be saved.
本发明公开了一种机制砂自密实堆石混凝土材料，该混凝土材料中，堆石体按体积率占50％‑55％，机制砂自密实混凝土占45％‑50％。所述机制砂自密实混凝土中各组分配比为：水泥530～560，矿粉85～105，粉煤灰70～90，硅灰55～65，砂690～720，碎石850～900，外加剂16.25～16.78，水140～160，单位均为kg/m3，还涉及到机制砂自密实堆石混凝土材料的制备方法。本发明制备出的机制砂自密实堆石混凝土材料具有良好的工作性能与力学性能，机制砂相比于天然砂的价格更低，能够节约工程成本。
