Research and Design on the Effect of Polycarboxylic Acid High Performance Water Reducer on the Durability of C60 High Performance Concrete
摘要: 本文研究了5种不同结构类型聚羧酸高性能减水剂对C60高性能混凝土耐久性能的影响，主要研究不同厂家的聚羧酸高性能减水剂对C60高性能混凝土耐久性(抗冻性、抗碳化性等性能)的影响。研究结果表明：不同种类的聚羧酸高性能减水剂对C60高性能混凝土抗冻性和抗碳化性影响不同，其中：掺A聚羧酸高性能减水剂的抗冻性最好，掺B聚羧酸高性能减水剂的抗碳化性能最好；掺B聚羧酸高性能减水剂的密实性能最好。
Abstract: In this paper, the effect of five kinds of polycarboxylic acid high performance water reducer on the durability of C60 high performance concrete was studied. And this paper mainly studies the effect of polycarboxylic acid high performance water reducer from different manufacturers on the durability (frost resistance, carbonation resistance, etc.) of C60 high performance concrete. Results show that different effects of polycarboxylic acid high performance water reducer on freezing resistance and carbonation resistance of C60 high performance concrete; Among them, polycarboxylic acid high performance water reducer A has the best frost resistance, and polycarboxylic acid high performance water reducer B has the best carbonation resistance, B polycarboxylic acid superplasticizer has the best compactness.
