摘　　要：全国各地夏季气温屡创新高,高温导致的混凝土坍落度经时损失严重影响了施工质量,为保证工地混凝土施工顺利,减少混凝土结构物质量隐患,分析不同混凝土原材料及环境条件下导致混凝土坍落度经时损失的原因。在不同温度环境下对混凝土坍落度损失的变化情况进行试验,通过调整减水剂不同组分进行混凝土坍落度损失情况试验及统计,分析其坍落度损失变化规律,降低混凝土坍落度损失。In order to ensure the smooth construction of concrete on the site and reduce the hidden dangers of concrete structure quality,the reasons for the loss of concrete slump caused by different concrete raw materials and environmental conditions were analyzed.The changes of concrete slump loss under different temperature environments were tested,and the concrete slump loss was tested and counted by adjusting the different components of the superplasticizer to analyze the change law of concrete slump loss and reduce the concrete slump loss.
