Test results concern modulus of elasticity and compressive strength of ordinary concretes made of various coarse aggregates from igneous rocks. Test results of some properties of these aggregates (3 crushed granites, 3 basalts, granodiorite, natural gravel) are also considered. The variable factor of the studies is the type of coarse aggregate. According to the analyses of regression and correlation there occurs a significant effect of the aggregate grinding ratio on the modulus of elasticity of concretes contrary to insignificant effect of the compressive strength. The modulus of elasticity of 4 concretes from Polish and Ukrainian granites and basalt aggregates is lower than respective standard values of the modulus.
