摘　　要：通过粉磨、分选等操作,制备不同粒径范围的矿渣粉,并将其部分替代水泥用于水泥砂浆的配制,研究矿渣粉的粒径特征对新拌及硬化砂浆性能的影响规律。结果表明,比表面积160-1 102 m2/kg之间,随着颗粒群细度增大,掺矿渣粉的水泥砂浆流动度降低,抗压强度增大,28 d硬化砂浆抗渗性先增大后降低。Several groups of slag with different particle characteristics are obtained through grinding and classifying,which are added in cement mortar.The effects of slag particle size on performance of both fresh and hardened mortar are studied. The results show that with specific surface area of slag particle swarm increasing from 160 to 1 102 mE/kg, fluidity and compressive strength of cement mortar increases while anti-permeability of 28 d cement mortar increases at first and then decreaseds.
