The authors have studied the development of a high-strength concrete mixture for manufacturing reinforced concrete products, in particular, the bar lintels. Dump fly ash of the Pavlodar CHPP-1 has been added as man-made waste. The paper presents the results of testing the concrete cubes strength with addition of industrial waste. The test results show the possibility of using anthropogenic waste for concrete mix in manufacturing bar lintels. In this case, the longer the hardening time, the higher the concrete mixture strength. By planning the experiment, a linear mathematical dependence of the concrete strength on such studied factors as cement, man-made waste and water, was obtained. The adequacy of the obtained model is confirmed by comparing the tabular and calculated values of the Fisher coefficient, as well as the coefficient of determination, which in practice varies for mixtures in the range from 0.7 to 0.8. According to the Pareto diagram, it is determined that all the factors are important, but the first component, i.e. cement consumption has the greatest effect. As a result, it was found that the addition of 10 % of man-made waste can reduce cement consumption by 10 % and increase the product strength by 20 %. Copyright
