摘　　要：研究了各种速凝剂对水泥强度的影响 .针对目前国内速凝剂存在的普遍问题 ,在反复试验研究的基础上 ,选出一种辅料 ,制成可降低速凝剂碱性、增加喷射料粘度的复合型水泥速凝剂———D型速凝剂 ,其强度保有率最高 ,同时研究了水灰比对掺有D型速凝剂的水泥强度的影响 ,试验结果水灰比越大 ,强度降低越多 .The effect of various quick_setting additives with the highest stability have been researched. As far as the quick_setting additive is concerned, a kind of material is selected by several times experiments. This kind of material can be made as the compound cement quick_setting additive——D_quick_setting additive which can decrease the alkalinity of the quick_setting additive but increase the viscosity of the jet materials. At the same time. cement water ratio on strength of cement including D_quick_setting additive are also researched. The result shows that the bigger the cement water ratio, the more the strength is lowed.
