温湿度对多哈港混凝土性能影响研究

Study of Temperature and Humidity on Properties of Concrete in Doha Port

针对热带沙漠地区的典型气候特点以及现场施工环境,利用温湿度交变试验箱,模拟施工现场的温度和相对湿度环境条件,研究C30,C40和C50强度等级混凝土在不同温度和不同湿度条件下的坍落度损失、凝结时间以及重塑时间的变化规律,为热带沙漠沿海气候区大体积混凝土施工质量控制提供参考依据。

According to the actual project Doha port andthe indoor environment parameters of the tropical coastal desert climate,the alternating temperature and humidity chamber is used to simulate the tropical desert climatefeatures for typical mix proportionof C30,C40 and C50 and study the effect on fresh concrete slump,setting time and remodeling time,Which provides the reference for quality control of mass concrete construction for coastal tropical desert climate.
