采用防冻剂与非引气型超塑化剂及超细沸石粉复合在最低温度为－３０℃条件下进行Ｃ３０级、Ｃ３５级负温砼冬期施工，实践表明，非引气型超塑化剂及超细沸石粉材料选择适当，掺量控制适宜时，免振自密实负温砼在浇注中等体积钢筋致密的水泥仓底座工程时是可行的。
The use of anti-freeze agents and non-bleeding superplasticizers and ultra-fine zeolite powders is used to carry out C30 and C35 negative temperature wintering constructions at a minimum temperature of -30°C. Practice shows that non-bleeding superplasticizers With the appropriate choice of ultra-fine zeolite powder material and appropriate control of the amount of material, vibration-free self-contained negative temperature crucibles are feasible when pouring medium-sized steel compact concrete tank foundations.
