  • Factors Affecting Strength And Workability Of Concrete

    Factors Affecting Strength And Workability Of Concrete

    strength and workability are both dominating factors in the making of concrete. strength can be increased by increasing cement content but this in fact reduces the workability. moreover,the water content can be increased for better workability, but this affects the strength.
