摘　　要：利用粉煤灰和矿渣取代100%熟料水泥,同时以再生细骨料替代部分天然砂,研究不同混杂激发剂掺入率对无熟料水泥砂浆的基础特性的影响,试验结果表明,无熟料水泥砂浆的稠度及强度均低于OPC,随着混杂激发剂掺入率的增加,砂浆的流动性逐步降低、强度逐步提高。This article utilized fly flash and slag to replace 100% of cement clinker,and used recycled fine aggregates to replace the part of nat-ural sands to study the effect on the basic characteristics of no cement mortars with different incorporation efficiency of mixed activators. The test results showed that,the consistency and strength of no cement mortars were lower than Ordinary Portland Cement（ OPC）. With the increase in the incorporation efficiency of mixed activators,the fluidity of mortars gradually reduced and the strength of mortars gradually increased.

关 键 词：混杂激发剂 无熟料水泥 稠度 抗压强度 抗折强度
