High-strength machine-made sand concrete and preparation method thereof
The invention relates to high-strength machine-made sand concrete, which is prepared from the following raw materials in percentage by weight: 16%-18% of cement, 3%-5% of a mineral admixture, 3%-5% ofmineral powder/stone powder, 20%-25% of machine-made sand, 3%-5% of a diluted epoxy resin, 40%-45% of a coarse aggregate, 0.3%-0.5% of a high-performance water reducing agent, 0.1%-0.3% of a curing agent and the balance of water. According to the high-strength machine-made sand concrete provided by the invention, the strength and workability meet the requirements of concrete standard specifications, the loss of a water reducing agent can be reduced, and the efficiency of the water reducing agent is improved.
本发明是关于一种高强机制砂混凝土，含有如下重量百分比的原料：水泥16％‑18％；矿物掺合料3％‑5％；矿粉/石粉3％‑5％；机制砂20％‑25％；稀释的环氧树脂3％‑5％；粗集料40％‑45％；高性能减水剂0.3％‑0.5％；固化剂0.1％‑0.3％；水为余量。本发明所提供的高强机制砂混凝土，其强度、工作性均符合混凝土标准规范要求，还能够减少减水剂的损耗、提高减水剂的效率。
