    Quizzical Pursuit
    —The Architecture Puzzler

    Created by Dave Guadagni

    Solution to Last Week's Puzzler
    Architecture Puzzler #269

    Question

    What is concrete curling and what is the typical cause?

    Answer

    Curling is the tendency for slab edges to bend up. It is usually caused by differential shrinkage of the cement paste in various parts of the slab. Basically, curling occurs when water leaves one side of a slab more rapidly than the other side.
