β-萘磺酸钠缩甲醛与木钙复合高效减水剂及其复合效应试验研究

The reasearch of compounded superplasticizer and its hybrid effect of calcium lignosulphnate and β-Naphthalence sulphnate

本文对木钙、萘系减水剂以及二者之复合减水剂的净浆流动度、混凝土减水率、混凝土强度进行了系统研究。结果表明 :木钙在较低掺量下可替代部分萘系减水剂 ,复合减水剂 (LS/PNS)的减水率有明显提高。

In this paper,mortar mobility?concrete water reducing rate and concrete compressive strength of calcium liggnosulphonate and naphthalence sulphnate admixture are systematically researched.The results show that calcium lignosulphonate in low addition can replace naphthalence sulphnate admixture partly.The water reducing rate of compounded superplasticizers increases obviously.
