Method for preparing conventional concrete from high-grade cement
The invention discloses a method for preparing conventional concrete from high-grade cement. The method comprises the following steps: 1), preparing Portland cement 42.5; 2), preparing common C15-C40concrete, mixing water, cement mortar prepared in the step 1, coal ash, mineral powder, sand, stone and an additive according to the mass ratio of (165-175): (30-80): (120-140): (130-220): (800-950):(900-1000): (6-10), and testing the compressive strength after 28 days to obtain the standard-meeting common concrete. According to the invention, the high-quality admixture is greatly mixed in the mixing station, so that cement components used by the concrete are clear, the concrete has good adaptability with additives, the high-quality high-performance concrete is prepared, the cost is saved, and profits are increased for enterprises.
本发明公开了一种高标号水泥配制常规混凝土的方法，包括以下步骤：步骤一：制备硅酸盐水泥42.5：步骤二：制备普通C15‑C40混凝土：将水：步骤一制得的水泥胶砂：煤灰：矿粉：砂：石：外加剂按照质量比165‑175：30‑80：120‑140：130‑220：800‑950：900‑1000：6‑10混合，待28天龄期后测试抗压强度得到符合标准的普通混凝土。本发明通过搅拌站大掺优质掺合料，使混凝土所用的水泥成分清晰化，同时和外加剂有着良好的适应性，配制出优质的高性能混凝土，并且节约了成本，为企业增加了利润。
