寒冷地区负温混凝土的工程应用

Engineering application of negative temperature concrete in cold places

结合五爱市场二期工程从混凝土浇筑的施工准备到施工质量控制这一整个冬季施工过程,通过现场混凝土内部温度测量和同条件养护试件留置来监控负温混凝土质量,指出同条件养护试件的试压强度不能作为混凝土质量的唯一依据,可供北方冬季施工参考。

Based on the process of the 2nd construction stage from the preparation to the quality control in Wu'ai supermarket project,the quality of negative temperature concrete through the measurement of interior concrete temperature on spots and specimen under the same curing condition were monitored.And it is also proposed compression strength of specimen under the same curing condition is not the only index,but a reference of the quality of concrete.
