摘要
速凝剂主要用于隧道、边坡等结构表面防护的喷射水泥混凝土,与普通水泥混凝土相比有其特殊性,如能参照规范合理选择喷射水泥混凝土的原材料,进行精确的配合比设计,正确选择喷射机械和工艺流程,严格控制喷射施工质量,就能达到设计效果,保证喷射水泥混凝土的施工质量。
Setting accelerator is mostly used in spray cement concrete for surface protection of tunnels, slopes and so on, which has its particularity compared with ordinary cement concrete. If raw materials of spray cement concrete are selected in reason referring to criterion, mix proportion is designed accurately, jet machineries and process flow are chose correctly and quality of spraying construction is controlled strictly, the design effect would be achieved, and the construction quality of spray cement concrete would be guaranteed.
