    How to Rapidly Speed Up Concrete Drying Time

    Concrete dries based on ambient conditions, not on a clock, per se. Reasonable air temperatures and relative humidity in the environment are more compatible with concrete drying. This being said, measuring the moisture in the concrete is the only way to know whether the conditions in the concrete are acceptable for the finish installation.
