Annotation The results of theoretical and experimental studies on the development of a scientifically grounded method of prescribing plasticizing chemical additives and mineral fillers in the selection of the compositions of complex-modified concretes (CMB) at the design stage are presented. The classification of plasticizing additives according to the degree of decrease in the surface tension of water upon their introduction and the activity of mineral additives according to the indicator of the reduced hydration activity, allowing to obtain highly economical MPC with the required properties.
