摘　　要：通过对聚羧酸减水剂与适量的缓凝组分及引气组分的外加剂进行复配系列试验,以净浆流动度、减水率、砂浆凝结时间及拌合物和易性等为指标进行系列试验,并对复配后混凝土的保坍性、和易性、力学性能、耐久性进行试验,结果表明复配效应达到预期效果。Based on the reduction of mixed polycarboxylic acid series of tests carried outwith retarded component sand airentraining admixture amount of components of the agent to cement paste fluidity,water reducing rate. The setting time of mortar and workability of series of experiments as the index. And the compound of concrete slump and workability and the mechanical properties,durability test.The results show that the expected results achieve a combined effect. Meet the mixture ratio design and construction requirements of high performance concrete
