Electric heat tracing curing is an effective method to avoid early freezing damage of concrete, improve cement hydration and concrete strength in winter construction in recent years. In order to improve the curing efficiency and effect, and optimize the electric heat tracing curing parameters under negative temperature environment, the air sandwich method and the built-in method were adopted to lay the electric heat tracing bands. The temperature change history and the cube compressive strength of C30 ordinary concrete during the heating curing process were obtained by taking the pre-curing parameters and constant temperature curing parameters as variables. The results show that the temperature distribution of specimens cured by air sandwich method is more uniform, and the compressive strength of concrete cubes increases by 7.6% compared with the built-in method. The optimal pre-curing time at 35 ℃ is 6 h, the pre-curing time increases, the cost increases, but the strength increases inconspicuously. When pre-curing at 10 ℃ for 6 h and constant temperature curing at 55 ℃ for 36 h, the strength is 81.5%fcu,k (cubic compressive strength standard value), which meets the requirements of plate mold removal strength. The purpose of this study is to provide reference for the design of concrete winter construction with electric heat tracing band, and then guide the construction method and engineering application.
