摘　　要：通过对比试验研究了速凝剂对水泥浆凝结时间、各龄期抗压强度的影响规律。结果表明:速凝剂能缩短水泥浆的凝结时间,提高其早期抗压强度,但会降低后期抗压强度;速凝早强剂能缩短水泥浆的凝结时间,提高其各龄期的抗压强度;速凝剂和速凝早强剂一定比例配合使用比单掺效果更好。The influence law of accelerator on curing time and compressive strength of cement slurry is studied by contrast test. The results show that accelerator can shorten the curing time of cement slurry and improve its early compressive strength, bur will reduce its late compressive strength; early strength agent can shorten the curing time of cement slurry and improve its compressive strength at different ages; the application effect of accelerator and early strength agent in a certain proportion is better than accelerator or early strength agent alone.

关 键 词：速凝剂 速凝早强剂 凝结时间 抗压强度
