    Quizzical Pursuit
    —The Architecture Puzzler

    Solution to Last Week's Puzzler
    Architecture Puzzler #433

    Question

    When you specify a seven-day water cure for concrete, about how much water does this require per square foot of concrete?

    Answer

    The seven-day concrete water cure has been a standard way of curing concrete since about 1910. It requires about five to eight gallons of water per square foot of concrete used over the seven-day period. This is a significant amount of water, and care must be taken in dealing with the alkaline water runoff. Note that if the concrete is allowed to dry out during the seven days, then proper curing will stop at that time and not resume properly even when concrete is re-wetted.
