aggregate crushing value vs compressive strength of concrete

    Relation Between Compressive and Tensile Strength of Concrete

    Jan 06, 2020· Compressive Strength The main measure of the structural quality of concrete is its compressive strength. This property of concrete is commonly considered in structural design. Depending on the mix (especially the water-cement ratio) and time and quality of the curing, compressive strength of concrete can be obtained up to 14,000 psi or more.
