摘要
以大同二电厂二期扩建工程为例,介绍了利用混凝土松弛特性来控制大体积混凝土裂缝的施工技术,分别阐述了控制混凝土产生裂缝的几种措施,包括优化配合比,控制入模温度,加强养护等,以期指导实践。
Taking the second extension project of No.2 power plant in Datong as the example,it introduces the construction technique to control the large concrete crack by using the relaxation property of the concrete,and illustrates the measures for controlling the concrete cracks,including the optimization of the proportional ratio,the control of the temperature in entering the model and the improvement of the maintenance,so as to direct the practice.
