| Abstract: | Thermal cracks are usually caused by excessive inside and outside temperature difference in concrete.This is an unavoidable problem in process of mass concrete construction.Water pipe cooling is an effective method to control the core temperature of concrete and avoid thermal crack.This method is applied in concrete construction of bridge pier cap,and the concrete temperature of pier cap is controlled in a reasonable limit.The monitoring results show that water piper cooling method is effective. |
