混凝土作为建筑工程中最常使用的材料,为我国的建筑事业作出了巨大贡献,而减水剂作为混凝土不可分割的组分,也得到了广泛的应用。聚羧酸高性能减水剂与萘系高效减水剂作为减水剂中常见的种类,对水泥净浆流动以及混凝土的各方面性能都产生着巨大作用。本文结合实际简单的介绍了萘系高效减水剂和聚羧酸高性能减水剂,简述了二者的相同性,并对它们之间存在优缺点进行了对比。 Concrete, as the most commonly used material in construction, has made a great contribution to China’s construction industry. As an integral part of concrete, water-reducer has also been widely used. Polycarboxylate superplasticizers and naphthalene superplasticizers are common types of superplasticizers, and have a huge impact on cement paste flow and concrete performance in all aspects. In this paper, the actual and simple introduction of naphthalene superplasticizer and polycarboxylate superplasticizer, the two are briefed on the sameness, and their advantages and disadvantages are compared.
