混凝土早强剂是一种可以加速混凝土早期强度发展的外加剂,对于加快工程进度,提高工程作业的周转率有重要作用,其掺量一般不会超过水泥质量的5%。首先对目前早强剂的种类和用量进行分类归纳,将早强剂分为无机、有机和复合3大类,并对不同种类早强剂的作用机理进行归纳总结,分析了不同研究者对早强剂应用性能的研究,指出目前早强剂存在的问题,为今后早强剂的研究和发展方向提供了参考。
Concrete early strength agent is a kind of admixture that can accelerate the early strength development of concrete. It plays an important role in accelerating the progress of the project and improving the turnover ratio of the engineering operation. The content of the concrete early strengthening agent is generally not more than 5% of the mass of cement. First of all, the type and amount of early strength agent are classified and summarized. The early strength agent is divided into three categories: inorganic, organic and composite. The mechanism of action of different types of early strength agent is summarized and analyzed. The research on the application of the strong agent shows that the existing problems of the early strong agent present the reference for the research and development of the early strength agent in the future.
