摘　　要：本文研究了不同类型的表面缓凝剂,不同的表面缓凝剂浓度,不同的养护温度在规定时间脱模后对混凝土的凝结时间和侧面冲刷效果的影响,得出在低温时蔗糖和某有机膦酸的凝结时间优异,侧面冲刷效果良好;高温时某有机膦酸效果优异。In this paper, the effects of different types of surface retarders, different concentrations of surface retarders and different curing temperatures on the setting time and side scouring effect of concrete after demoulding were studied. An organic phosphonic acid has excellent effect.
