摘　　要：　本文试验了几种无机和有机缓凝剂及其双组分复合缓凝剂的系列性能。结果表明双组分复合缓凝剂显著延长混凝土凝结时间达16～20小时,而不降低混凝土各龄期强度,达到低掺量超缓凝的效果。This paper has experimented with several kinds of organic and inorganic setting retarders,and the hybrid setting retarder of two types.The conclusion shows that the hybrid setting retarder obviously delayed setting time up to 16～20hr,and didn't reduce the compressive strength of concrete in different periods.This test has reached the good result,which is low dosage,extralong setting retarding time.
