以粉磨时间分别为40 min和60 min的石屑石粉、市售石粉以及机制砂石粉为对象，研究不同种类石粉单掺或者与粉煤灰、矿粉复掺以及三掺时，在不同掺量下对水泥基砂浆的力学性能的影响。结果表明，掺合料三掺时水泥基砂浆表现出最佳力学性能；石粉与粉煤灰和矿粉的激活效应是相互的。

This paper adopted two stone chip powders (grinding respectively for 40 min and 60 min), commercial limestone powder and machine-made sand powder as the research object to focus on the study of the mechanical property of cement-based mortars when different kinds of limestone powders mixed single or together with other mineral admixtures such as lfy ash and slag powder. Experimental results showed mortars had the best mechanical property when the three mixed together. The activation effect between limestone powder and the mineral admixtures powder was mutual.
