摘　　要：介绍了一种混凝土复合矿物掺合料活性指数的检测方法,采取复合矿物掺合料等体积替代水泥检测混凝土复合矿物掺合料的活性指数,按此方法检测可以合理地解决复合矿物掺合料因密度波动对复合矿物掺合料活性指数产生的影响,进而可以将不同矿物掺合料的活性指数检测方法统一,有利于扩大工业废弃物资源利用的范围,便于复合矿物掺合料产品标准的设立及应用。A new detection method of activity index of concrete composite admixture is described. Specifically,cement is rc- placed with an equal volume of compound mineral admixture to detect activity index of concrete composite admixture. The negative effects in activity index measurement due to density change of compound mineral admixture can be eliminated with this method, and then,different detection methods of concrete composite admixture can be unified,which is benefit for resource utilization of industrial waste,and contributes to establishment and application of standards in concrete composite admixture product.
