This paper addresses the issue of the influence of cement consumption, plasticizing additive, and compaction time on the strength and frost resistance of concrete manufactured with bottom ash slags from thermal power plants. The investigation was carried out using the three-factor experiment with variables varied at three levels. There were received response functions, which characterize the correlation between frost resistance and variables: cement consumption, plasticizer additives and compaction time. An analysis of the surface of the response function, where the frost resistance of the concrete was accepted as a response, revealed the optimal correlation between the components of the mixture and the compaction time of the seal. By using the STATISTICA 12 software complex, the values of the factors were specified, when the optimal components ratio with GLENIUM 51 superplasticizer is achieved for the production of concrete with high frost resistance that is greater than F300. The conclusions quantify the results of the investigation.
