Abstract：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/m2): SL2(460 kg/m2): SL3(570 kg/m2) :S = 1:3:1:5.
