摘要
大体积混凝土施工容易产生温度裂缝,为了保证工程质量,避免温度裂,关键在于使混凝土内部与表面温差小于25℃或降低温度应力,提高混凝土的抗拉强度。本文介绍了阜新市人防工程大体积混凝土底板施工中所进行的温度裂缝预测以及采取的一系列施工技术措施。
The mass concrete tends to produce temperature crack during construction,in order to ensure engineering quality and avoid temperature crack , the following key measures shoud be taken： the difference between inner and outer temperature of concrete shoud be controlled less than 25℃, the tempereture stress shoud be decreased and the concrete tensile strength shoud be improved. This article introduced a series of technical measures in the construction of mass concrete bottom,which is a part of men-saving project in Fuxin,such as predicting temperature crack etc.
