2020121· Properties of concretes are consistent with aggregate strength. The strongest impact of aggregate crushing resistance on concrete modulus of elasticity was found. A similar strong impact applies to tensile strength of concretes, while effect of crushing resistance on compressive strength of concretes was just moderate.
