摘要
在建筑工程基础大体积混凝土施工时,混凝土的温度计算不容忽视.可通过对混凝土拌合温度计算、出罐温度计算、绝热温升计算、中心最高温度及表面温度的计算,对底板中心温度和表面温度的差值,混凝土表面温度和大气温度的差值与规定值进行比较,如果均小于25℃,则达到规定要求,设计方案可行.
When the large volume concrete building base is poured, it should not neglect the temperature calculation of concrete crevices. Through caculating the concrete mixing temperature, the leaving pot temperature calculation ,absolute temperature gone up,the central maximum temperature and the face temperature, we can compare not only the D-value between the central tempreture and face tempreture of the baseboard but also the D-value between the face temprefure of concrete and air cempreture.If both of them are smaller than 25℃,it means that the designing plan meets the requirements and is feasible.
