M(t) = X (T a T o) T (1) Where, M(t) = maturity (degree-hours), T a = average concrete temperature during interval F, T o = datum temperature (14 F) and = time interval (hours). To account for the e ect of initial curing temperature on the strength development of concrete at di erent ages, a concrete factor is suggested.

  • When to Start Curing of Concrete?

    When to Start Curing of Concrete?

    In short, the curing should start after minimum six hours (Final setting time of cement) and not less than 24 hours. Thus, when concrete curing has to start is varies and depends on when the surface of the concrete begins to dry. Concrete curing should be started before concrete surface loses its water and undergo shrinkage.

    TIPS TO CURE CONCRETE IN COLD WEATHER

    Jan 06, 2016· Curing concrete becomes a more challenging job in colder days. Heavy snowfall and excessive humidity in the air are a few typical sights of the winter season which prevent concrete slabs from hardening properly in time. When temperature goes below 0 degree Celsius or minus 7 degree Celsius, it impacts concrete curing severely.
