The aim of this study was to determine the impact of mechanical properties of aggregates on ordinary and high performance concretes with these aggregates. Research included aggregate crushing resistance and mechanical properties of 24 concretes with: basalts, granites, granodiorite, dolomite, quartzite, gravels from 13 Polish and Ukrainian mines. 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.
