结合实践经验，探讨了 CS 促凝剂的作用，阐述了水泥强度试验的准备工作、试验步骤和抗压强度的测定过程，并根据试验数据统计结果及试验验证，得出以1 h 推定水泥28 d 强度误差较小，适用于混凝土生产企业控制混凝土质量的结论。%Combining with the practical experience,the paper explores the role of the CS coagulant,illustrates the preparation,the test steps, measurement process of the anti-compression strength of the cement strength tests,and concludes the 28 d strength errors induced by 1 h is smal-ler,so it can be adopted in the control over the concrete quality in the concrete production enterprises according to the results of the test data sta-tistics and test features.
