沙特阿拉伯王国大部分地区属热带沙漠气候,夏季炎热干燥,最高气温可达50℃以上,水分蒸发快,现浇混凝土施工因气温高、水分蒸发快易产生收缩裂缝,该文介绍了沙特南北铁路在夏季高温条件下如何确保现浇混凝土施工的质量控制措施,通过有效控制原材料温度、设备温度及环境温度,延缓了混凝土凝结时间,确保了混凝土顺利泵送和浇筑质量。 Most of the Kingdom of Saudi Arabia is a tropical desert climate, hot and humid in summer, the maximum temperature can reach above 50 ℃, the water evaporates fast, the construction of cast-in-place concrete due to high temperature, water evaporation prone to shrinkage cracks, this article describes the Saudi North-South Railway How to ensure the quality control measures of cast-in-place concrete under high temperature in summer, to delay the setting time of concrete by effectively controlling the temperature of raw materials, equipment temperature and ambient temperature so as to ensure the smooth pumping and pouring quality of concrete.
