摘要
主要探讨了聚羧酸减水剂的工作原理,以及在混凝土施工中的应用,通过试验和理论分析,研究了聚羧酸减水剂对混凝土用量、强度、耐久性、早期强度和硬化时间等方面的影响,提出了减水剂用量及混凝土配比的优化建议。
This paper mainly discusses the working principle of polycarboxylic acid superplasticizer and its application in concrete construction.Through test and theoretical analysis,the influences of polycarboxylic acid superplasticizer on the dosage,strength,durability,early strength and hardening time of concrete are studied,and suggestions for optimizing the dosage of superplasticizer and the ratio of concrete areput forward.
