摘　　要：本文主要研究了石粉对水泥-矿粉混凝土的工作性、抗压强度、耐久性能(抗渗性能、抗碳化性能和抗冻性能)的影响,并利用孔结构微观分析对其进行了机理分析。研究表明:石粉应用于水泥-矿粉混凝土中,不仅可改善混凝土的工作性能,而且可提高混凝土的抗压强度,对混凝土的耐久性能(抗渗性能、抗碳化性能和抗冻性能)影响不大。Influence of limestone powder on the workability, compressive strength, and durability （impermeability in water, carbonation resistance and freezing resistance） of cement-slag concrete was studied, and the acting mechanism was also researched by analysis of pore structure. Results show that workability and compressive strength of cement-slag concrete are improved and durability does not change much when mixing with limestone.
