This article describes the study of the dependence of the tensile strength Rbtn on the class B concrete. After carrying out experiments on the prism beams, the effect of concrete compression on its tensile strength was evaluated. The test results showed that the preliminary compression of concrete has a negative effect on the tensile strength of concrete, which begins to manifest itself at σvr/Rvr ≥ 0,15.
