聚羧酸减水剂作为高性能减水剂,已广泛应用于工民建、高速铁路、核电等工程中。将其加入至混凝土中,不仅能增加新拌混凝土的流动性与和易性,还能增加硬化混凝土的后期强度。然而随着聚羧酸减水剂研究不断深入,聚羧酸减水剂被发现对骨料中粘土含量较高的混凝土适应性较差,会导致新拌混凝土的初始坍落度较小, Polycarboxylate superplasticizer as a high performance water reducer, has been widely used in workers civil construction, high-speed railway, nuclear power and other projects. Adding it to the concrete not only increases the fluidity and workability of the fresh concrete, but also increases the later strength of the hardened concrete. However, with the continuous research of polycarboxylate superplasticizer, polycarboxylate superplasticizer has been found to have poor adaptability to the concrete with higher clay content in the aggregate, resulting in less initial slump of fresh concrete,
