Four hours after the concrete pouring of the main side wall of Wenyang Road Station, Cao Wenwu had already stood next to the initially set side wall with a thermometer.
The numbers on the screen made him furrow his brow: the temperature of the C45P8 concrete core was 52.
9 ℃, while the surface was only 31.
8 ℃.
The temperature difference of 25 ℃ was like an invisible crack, growing bigger and bigger in his heart.
As the team leader of the concrete team in Section 06 of Qingdao Metro Line 15, this is not the first time we have encountered a similar situation this month.
Looking at the temperature measurement data that exceeded the standard, it was as if he could see the slow development of cracks inside the concrete, which was another challenge he and his team encountered in the trial of decorative concrete.
