大体积混凝土冬季施工技术

Construction Technology for Big Volume of Concrete in Winter

大体积混凝土的裂缝控制问题,是一项国际技术难题。理论成果很多,但在施工中仍然难以依据某一理论来指导现场施工。结合工程实际介绍了筏板基础大体积混凝土冬季施工如何从原材料选择、温度控制以及施工组织等方面控制大体积混凝土温度裂缝。

How to control big volume of concrete is an international difficult question. There are many theoretical achievements, but it is very difficult to be on the basis of one theory to direct construction. The const ruction technology for the big volume of concrete foundation in winter, such as how to control temperature cracks by means of selection of raw materials, temperature control and construction organization is discussed.
