  • Tips for Curing Concrete in Cold Weather

    Aug 23 2019 · The process of curing concrete becomes more challenging in cold weather since to properly set and reach maximum strength fresh concrete must be protected from freezing for at least the first 24 hours or until it reaches a minimum strength of 500 pounds per square inch (psi). Concrete that freezes at an early age can lose much of its overall strength.

    Sep 22 2016 · If the hardening process occurs at a low temperature the final strength won t be affected though the development of the strength is slow. But if the temperature is under 0 0 C the hydration of cement will stop and the strength will not only stop growing but also destroy the structure of cement paste due to the condensation of water.
