摘　　要：通过对五个厂家的速凝剂与不同新鲜程度的基准水泥的检测进行了分析,结果表明:随着基准水泥存放时间的延长,速凝剂的初凝时间和终凝时间均会延长,初凝时间最高延长3 min以上,终凝时间的最高延长10 min 6 s;1 d抗压强度最高降低14.9%,28 d抗压强度比有提高的趋势,最高可达11%。Through the detection results analysis on accelerator of five manufacturers and the reference cement of different freshness, results showed that： with the storage time increases of reference cement, the initial setting time and final setting time of accelerator were prolonged, the initial setting time maximum extension of more than 3 min, the final setting time maximum extension of 10 min 6 s, 1 d compressive strength high-est decreased 14.9%, the 28 d compressive strength ratio had a trend of increase, up to maximum of 11%.
