| Abstract: | The demanding of construction technology for large volume concrete in passenger dedicated line engineering is higher.However,the heat of hydration of cement and other problems caused by temperature stress crack can seriously restrict the quality of the project.This paper makes a qualitative analysis on the cracks in big volume concrete.Combined with concrete core temperature,temperature calculation value of stress on the project,comprehensive control of hydration heat of cement production from design to construction,it effectively improves the construction quality of large volume concrete. |
