    Concrete: Scientific Principles

    Concrete Summary. Once set, concrete continues to harden (cure) and become stronger for a long period of time, often up to several years. The strength of the concrete is related to the water to cement mass ratio and the curing conditions. A high water to cement mass ratio yields a low strength concrete.
