  • 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.
