  • Concrete 101 | Centre Concrete

    The watercement ratio is the ratio of the weight of water to the weight of cement used in a concrete mixture. This is critical to the overall quality of the concrete. A lower water cement ratio allows for increased compressive and flexural strength, reduced shrinkage cracking, lower permeability, and a better resistance to wear ad weather.
