浇筑温度和养护凝固方式对混凝土的性能影响很大。本文结合工程实际，研究了高温环境下，混凝土初始浇筑温度分别为25℃、32℃和38℃，各自采用浸水养护、湿粗麻布覆盖养护、涂水基凝固剂密封养护等三种方法，通过测量3天、7天、28天、90天及180天的抗压强度，评估浇筑温度和养护凝固方式对所研究混凝土性能的影响。结果表明该条件下混凝土初始浇筑最佳温度为32℃，浸水养护凝固能产生最好的混凝土，而湿粗麻布覆盖养护方法应优先于添加凝固剂养护的方法。
Pouring temperature and curing method have great influence on the performance of concrete. In this paper, combined with the construction practice, the initial pouring temperature of concrete in high temperature environment is 25？C, 32？C and 38？C. Three methods are adopted including soaking curing, wet burlap covering curing and water-based coagulant sealing curing. The compressive strength of concrete in 3 days, 7 days, 28 days, 90 days and 180 days is measured to evaluate the influence of pouring temperature and curing method on the performance of concrete. The results show that the best initial pouring temperature of concrete is 32？C. The best concrete can be produced by soaking curing, and the curing method of wet burlap covering should be prior to the curing method of adding coagulant.
