A hypothesis that concerns concrete strength is proposed based on testing under compression with elimination of surface friction. Three basic parameters are used: splitting strength of aggregate, tension strength of mortar or cement-stone, and adhesion between aggregate and mortar or cement-stone. The structural stresses from shrinkage of concrete are taken into account, and the degree of relaxation with time is evaluated. The hypothesis, which is confirmed by experimental results of testing concrete made with aggregates from several rocks, is used for producing high-strength concrete.
