摘 要:以石灰石粉等量取代部分水泥,分析了混凝土的工作性能和力学性能的变化规律,探讨了用石灰石粉部分取代水泥在商品混凝土中应用的可行性。结果表明,在掺加聚羧酸外加剂的C30和C35混凝土中以15~35kg/m3的石灰石粉等量取代水泥是可行的。在商品混凝土中使用石灰石粉部分取代水泥可降低每m3混凝土原材料成本,并可充分利用我国丰富的石灰石资源。
Abstract: Limestone powder was used to replace some cement, and the effect of concrete on the properties of concrete was detected. In order to discuss the feasibility of replacing, the changes in the workability and mechanical properties of concrete were analyzed. The results show that it's feasible to replace cement with 15~35kg/m3 limestone powder in C30 and C35 concrete. The use of limestone powder instead of cement can reduce the cost of concrete and make full use of the abundant limestone resources in our country.
