Limestone machine-made sand concrete and preparation method thereof
The invention discloses limestone machine-made sand concrete, which is prepared from the following materials in parts by weight: 300 to 400 parts of limestone machine-made sand, 200 to 350 parts of coarse aggregate, 150 to 200 parts of fine aggregate, 120 to 180 parts of cementing material, 10 to 15 parts of water reducing agent and 30 to 40 parts of water. The cementing material comprises the following materials in parts by weight: 20-40 parts of fly ash, 15-20 parts of cement, 25-35 parts of slag powder and 10-15 parts of water. Traditional river sand is replaced, limestone machine-made sand is used, raw materials are rich and low in cost, and the production cost of the concrete is effectively reduced.
本发明公开了一种石灰石机制砂混凝土，包括下述重量份数的材料：石灰石机制砂300‑400份、粗骨料200‑350份、细骨料150‑200份、胶凝材料120‑180份、减水剂10‑15份、水30‑40份。胶凝材料包括下述重量份数的材料：粉煤灰20‑40份、水泥15‑20份、矿渣粉25‑35份、水10‑15份。本发明代替传统河砂，使用石灰石机制砂，原料丰富成本低廉，哟有效降低混凝土的生产成本。
