  • Temperature and relative humidity What they mean for you

    Concrete needs to remain moist in order for it to cure. Generally the internal relative humidity needs to be above 80 to 85 relative humidity for hydration to take place. Wetting the surface of bare concrete creates a barrier of water that prevents the moisture from inside the concrete from being drawn out when the surface moisture evaporates.

  • Tips for Curing Concrete in Cold Weather

    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.
