Machine-made sand concrete and preparation method thereof
The invention relates to concrete, in particular to machine-made sand concrete and a preparation method thereof. The concrete comprises the following materials in parts by weight: 320-330 parts of cement, 60-70 parts of mineral powder, 40-50 parts of fly ash, 710-730 parts of sand, 1050-1100 parts of gravel, 165-175 parts of water, 8-9 parts of an admixture and 100-110 parts of water absorption blocks. The admixture improves the flowability of the concrete and delays the hydration process, so that the concrete is not easy to bleed, and the workability is improved. The added water absorption blocks can be used as a lubricating substance of machine-made sand, and the water absorption blocks are not completely saturated at the moment and can continuously absorb bleeding water or redundant water in the concrete, so that the workability is further improved.
本发明涉及混凝土，尤其是一种机制砂混凝土及其制备方法；它包括以下重量份数的物料：水泥320‑330份、矿粉60‑70份、粉煤灰40‑50份、砂710‑730份、碎石1050‑1100份、水165‑175份、外加剂8‑9份、吸水块100‑110份。外加剂提高混凝土的流动性和延缓水化过程，这样混凝土就不容易泌水，提高了和易性；吸水块的加入则可作为机制砂的润滑物质，并且吸水块此时并未完全饱和，还可以继续吸收混凝土中泌水或者多余的水，从而进一步提高和易性。
