摘　　要：研究了废砖粉物理特性、微观结构、化学成分,废砖粉潜在活性,并通过实验获得废砖粉活性指数。结果表明:粉磨可从物理角度极大地激发废砖粉潜在的水化活性,磨细废砖粉活性指数最大能达到81%。废砖粉具有优质矿物掺合料的潜质。The physical properties, microstructure and chemical composition of the recycled brick powder are studied. And the activity index is obtained through experiment. The potential hydration activity of recycled brick powder can be greatly excited through grinding from the point of the physical; the maximum activity index can reach 81%with high quality.
