The results of the research strength of the concrete in the construc-struction using a systematic approach. It is shown that the current model of the prize-strength variable with the empirical dependence of the concrete class does not take into account the effect of the variability of the strength of concrete. A probabilistic model coefficient prism strength given its dependence on the concrete homogeneity.
