摘　　要：将不同比表面积的石灰石粉按不同比例掺入水泥中,对水泥的性能进行研究。结果表明:石灰石粉的加入,能有效提高水泥的外加剂相容性、促进水泥的水化及提高水泥胶砂的体积稳定性;一定颗粒分布的石灰石粉对水泥胶砂的流动性能及强度有促进作用。The limestone powders with different specific surface area and proportion were mixed into cement to research their performance. The results showed that the limestone powder could effectively improve the adaptability of cement with concrete admixture, promote the hydration of cement and increase the volume stability of cement mortar. The limestone powder with a certain particle size distribution could improve the fluidity and strength of cement mortar.

关 键 词：比表面积 石灰石粉 强度 水化热
