摘　　要：胶凝材料的细度、颗粒形貌和颗粒分布是影响胶凝材料各项性能的一个重要因素。本文以不同比表面积的矿渣粉为研究对象,通过激光粒度分析法对胶凝材料活性进行研究。研究结果表明:不同比表面积的矿渣粉按适当比例掺配,可有效提高水泥矿渣粉胶砂的力学性能,优化矿渣粉活性。矿渣粉与基准水泥最优的复合比例为SL1(300 kg/m^(2))∶SL2(460 kg/m^(2))∶SL3(570 kg/m^(2))∶S=1∶3∶1∶5。The fineness,particle morphology and particle distribution of cementitious materials are important factors affecting the properties of cementitious materials.In this paper,slag powder with different specific surface area was used as the research object to study the activity of cementitious materials by laser particle size analysis.The results show that proper mixing of slag powder with different specific surface area can effectively improve the mechanical properties of cement slag powder mortar and optimize the activity of slag powder.The optimal composite ratio of slag powder and reference cement is SL1(300 kg/m^(2)):SL2(460 kg/m^(2)):SL3(570 kg/m^(2)):S=1:3:1:5.
