本文通过利用新疆本地的原材料来研究应用聚羧酸减水剂与萘系减水剂对水泥净浆和混凝土性能不同的作用效果,以及聚羧酸、萘系减水剂对混凝土耐久性能的影响,并应用于工程实践。结果表明:与萘系减水剂相比,聚羧酸减水剂对水泥颗粒有更好的分散性能和流动度保持性能,减水率高,增强效果明显,坍落度保持久,能够改善混凝土耐久性,聚羧酸系减水剂在预拌混凝土中应用前景看好。
In this paper, through the use of local raw materials in Xinjiang to study the application of polycarboxylate superplasticizer and naphthalene superplasticizer on the performance of the cement paste and concrete different effects, as well as polycarboxylic acid, naphthalene superplasticizer on the durability of concrete , And applied to engineering practice. The results show that compared with naphthalene superplasticizer, the polycarboxylate superplasticizer has better dispersibility and fluidity retention properties for cement particles, high water reducibility, obvious enhancement effect, long slump retention and improved Concrete durability, polycarboxylate superplasticizer in the ready-mixed concrete application prospects.
