Research on Early Concrete Crack Control of Shijiazhuang Subway Construction in Winter

摘要

The control of concrete cracking is a complicated and difficult problem for civil engineering. It is more difficult to control the cracking of the concrete poured in the winter. Thorough the analysis of the construction of the Shijiazhuang subway in winter, several methods are integrally applied. Frost proof and decreasing the temperature stress of concrete is considered together. The construction quality of the concrete arrive a satisfied level and the cracking of the concrete is successfully handled.
