Abstract
Analysis the factors of mass concrete temperature crack. Combined with the Nan Yang Branch of CUCC cement clinker production line of the second phase of mass concrete construction, it proposed some measures about how to prevent the temperature stress crack of mass concrete due to hydration heat of cement generated temperature difference .By controlling the temperature of the concrete strictly, decreasing the temperature difference between inside and outside, preventing shrinkage joint, reducing the slump loss, delaying setting time, etc. To ensure from the construction maintaining process of mass concrete foundation floor, the tensile strength of concrete is always greater than the maximum temperature tensile stress to prevent temperature cracks appear ensure the quality of mass concrete construction.
