Machine-made sand concrete and preparation process thereof
The invention relates to the field of concrete, and particularly discloses machine-made sand concrete and a preparation process thereof. The machine-made sand concrete is prepared from, by weight, 250-350 parts of Portland cement, 50-80 parts of fly ash, 1000-1200 parts of coarse aggregate, 700-800 parts of machine-made sand, 3-5 parts of a water reducing agent and 160-170 parts of water, the machine-made sand is prepared from iron ore tailings, and the stone powder content of the machine-made sand is 1%-9%. The machine-made sand concrete has the advantage that the problem that the slump of the concrete is reduced due to addition of machine-made sand is solved.
本申请涉及混凝土领域，具体公开了一种机制砂混凝土及制备工艺。机制砂混凝土，按重量份计，包括硅酸盐水泥250‑350份、粉煤灰50‑80份、粗骨料1000‑1200份、机制砂700‑800份、减水剂3‑5份和水160‑170份，所述机制砂由铁矿石尾矿制得，所述机制砂的石粉含量为1%‑9%。本申请的机制砂混凝土具有解决机制砂加入导致混凝土坍落度降低的问题的优点。
