    Quizzical Pursuit
    —The Architecture Puzzler

    Created by Dave Guadagni

    Solution to Last Week's Puzzler
    Architecture Puzzler #388

    Question

    Why do you typically want to keep concrete from freezing during the first 24 hours after placement?

    Answer

    The water in concrete can freeze, and if it does, it will stop the chemical curing process and keep the concrete from reaching design strength.
     


     

    Okay, got it? Now try this week's Puzzler:
