摘要
本文介绍了聚羧酸系减水剂的性能特点及研究状况,并在此基础上,研究了聚羧酸系高效减水剂与萘系、氨基磺酸盐系及脂肪族系高效减水剂复合使用对水泥净浆流动度的影响。结果表明:聚羧酸系高效减水剂与萘系及氨基磺酸盐系高效减水剂的复合效应差,而与脂肪族系高效减水剂的复合效应较好。
In this paper,the performance characteristic and the research progress of polyacrylic-based superplasticizer were introduced.Based on the above,the influences of polyacrylic-based superplasticizer compounded with naphthalene-based, amino-based and aliphatic-based superplasticizers on the fluidity and the fluidity loss of cement pastes were investigated. The results show that the compounding effects of polyacrylic-based superplasticizer with naphthalene-based and amino- based superplasticizers are bad,but the the compounding effects of polyacrylic-based superplasticizer with aliphatic-based superplasticizer are good.
