摘要
速凝剂是喷射混凝土的重要组成部分,速凝剂的质量直接关系到喷射混凝土质量的好坏。根据不同的分类标准介绍了速凝剂的分类,对传统速凝剂存在的问题进行了总结,指出了新型速凝剂的发展方向,并对不同种类的速凝剂的促凝机理进行了详细阐述。
Setting accelerator is an important part of shotcrete. The quality of shotcrete is directly related to the quality of setting accelerator. This paper introduced the classifications of setting accelerator according to different standard. The existing problems of traditional setting accelerator were summarized. The development direction of new accelerator was pointed out. At last,the accelerating mechanisms of different kinds of setting accelerator were described in detail.
