缓凝剂对水泥混凝土性能影响的试验研究

Test and Research on Retarder's Influence to Cement Concrete Performance

研究了几种常用缓凝剂对水泥混凝土性能的影响,以及缓凝剂与水泥不适应对混凝土工作性和强度的影响,分析了缓凝剂与水泥不适应的影响因素及机理,提出了预防和处治混凝土的异常凝结的措施,供缓凝剂工程应用时参考。

This paper studies influence of several often used retarders on cement concrete performance, and influence on working performance and strength of concrete due to improper use of retarder for cement. Furthermore, it analyzes influence factor and mechanism for improper matching of retarder and cement, and suggests measures to prevent and treat abnormal setting of concrete, for reference in retarder project.
