摘要
目前聚羧酸减水剂的应用主要集中在高强度的高性能混凝土工程中,而在量大面广的中低强度等级混凝土中的研究还比较少。本文主要研究了聚羧酸减水剂在中低强度等级混凝土中的应用,聚羧酸减水剂可以改善新拌混凝土的综合性能,提高与掺合料的适应性,增强混凝土的耐久性。
Polycarboxylate superplasticizer is mainly focused on the application of high strength and high performance concrete engineering,which fewer research on the low-strength-grade concrete.This paper mainly studies the polycarboxylate superplasticizer in low-strength-grade concrete application,which can improve the comprehensive performance of mixing concrete,the adaptability with admixture,and enhance the durability of concrete.
