| Abstract: | Taking the construction of water-proof concrete on main structure of line 2 of Xi＇ an subway as an example, reasons for the appearance of cracks on water-proof concrete are analyzed. Integrative preventative approaches are presented in aspects including the quality control of major materials of concrete, determination of cementitious materials and water-binder ratio, as well as the configuration of concrete and construction requirement, so as to solve the problem of cracks and make sure of the service life of concrete structure. |
