【摘要】: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。
[Abstract]:In view of the typical climatic characteristics of tropical desert area and site construction environment, the temperature and relative humidity environmental conditions of construction site are simulated by using the temperature and humidity alternating test box. The changes of slump loss, setting time and remolding time of C _ (30) C _ (40) and C _ (50) strength grade concrete under different conditions of temperature and humidity are studied, which provides a reference basis for the construction quality control of mass concrete in the coastal climate area of tropical desert.
