摘　　要：研究了用废弃黏土砖制作混凝土矿物掺合料的试验研究。试验结果表明废砖的粉磨能耗仅为水泥熟料的5%;细粉磨比粗粉磨更能激发废砖粉的活性;废砖粉替代水泥的掺量在30%以内时,能够提高砂浆的抗折强度。This paper introduces the experimental study on making concrete mineral admixture by waste clay brick.The test results show that the energy consumption of waste brick is only5%of cement clinker.Fine grinding can stimulate the activity of waste brick powder more than coarse grinding.When the amount of waste brick powder instead of cement is less than30%,the flexural strength of the mortar is increased.

关 键 词：废砖粉 粉磨能耗 活性 细粉磨
