水泥与高效减水剂相容性的研究

从混凝土减水剂和水泥两方面论述了导致减水剂和水泥不相适应的原因，分析聚羧酸系高效减水剂优于萘系减水剂的机理，另外，还就掺加高效减水剂后混凝土坍落度损失过快的原因、机理及对策进行了探讨。

Compatibility between Concrete Admixtures and Cement

The factors leading to the compatibility between superplasticizers and cement were discussed. The mechanism for the superiority of multi -carboxylic acid based superplasticizers to sulphonated naphthalene based superplasticizer was analyzed. In addition, the reasons and the mechanisms of the greater slump-loss of concretes added with superlasticizers were summarized, and some valid measures which could be used to control the slump-loss of the concretes were proposed.
