摘　　要：研究了高活性矿物掺合料浆的制备过程及其对净浆基本性能、水化热、化学收缩及混凝土制品强度的影响。结果表明:高活性矿物掺合料浆按固含量替代10%～30%的水泥可配制出C30～C50的高性能混凝土,其工作性及后期性能均达到了国家标准,实现了低水化热、低收缩、低成本的应用效果。The preparation process of the high active mineral admixture slurry was studied. And the influence towards basic performance of past, hydration heat, chemical shrinkage and strength of concrete were studied too. The results indicated： the high active mineral admixture slurry solid content could substitute 10%-30% cement to product the high performance concrete of C30-C50, its workability and the later performance had achieved the national standards, and has realized the low hydration heat, the low chemical shrinkage and the low cost application effect.
