摘　　要：　对缓凝剂进行试验和分析,并配置缓凝型减水剂,对混凝土的性能进行分析。提出配置缓凝型减水剂应综合考虑缓凝时间要求、坍落度损失和水泥品种。在试验和生产对比中应考虑商品混凝土运输对混凝土的影响。Experiment and analysis were set for retarder,and retarding plasticizers were matched to analyze the concrete performance.It proposed that considerations on retarding time,slump loss and cement kinds are important for retarding plasticizer matching.Effects by transporting also should be regarded for ready-mixed concrete in trials and producing.

关 键 词：商品混凝土 缓凝 配合比 坍落度损失
