Study on Freeze-Thaw Relationship of Concrete under Laboratory and Natural Conditions

Through field sampling and testing, the relationship between the number of freeze-thaw cycles of hydraulic concrete in actual environment and number of freeze-thaw cycles under laboratory conditions is established to solve the problem that the structure durability of hydraulic concrete in Jilin Province is degraded due to freeze-thaw damage. In this way, people can predict the number of concrete cycles in the actual engineering environment through freeze-thaw cycle parameters in laboratory tests, and put forward an economical and reasonable management and operation plan, which is of great significance in engineering.
