DEVELOPMENT OF A METHODOLOGY FOR PREDICTING THE PROPERTIES OF MULTICOMPONENT HIGH-QUALITY CONCRETE TAKING INTO ACCOUNT THE SURFACE PROPERTIES OF MINERAL FILLERS AND STRUCTURAL SIMULATION MODELING

The results of theoretical and experimental research on the development of a scientifically based methodology for prescribing plasticizing chemical additives and mineral fillers in the selection of compositions of complex modified concrete (CMC) at the stage of their design are presented. A classification of plasticizing additives is proposed according to the degree of reduction in the surface tension of water upon their introduction and the activity of mineral additives according to the indicator of reduced hydration activity, which makes it possible to obtain highly economical BMPs with the required properties.
