Based on the research performed, a comparative analysis of the changes in the properties of activated and non-activated fine-grained mixtures and mortars depending on the different specific surface: fine fillers: finely ground tripoli or sand, as well as on the content of inorganic PFM: highly active meta-kaolin, wollastonite and super-plasticizing additive superplasticizer S-3 or Melflux. The carried out researches show wide possibilities of modification of compositions by organomineral ecologically harmless additives and testify to rationality of development of complex additives separately for the activated and not activated fine-grained mortars. It is shown that when switching to another type of filler, even the same chemical composition, the dosages of all components and their ratio should be adjusted optimally. When switching to another type of mixture preparation, the ratio of components. Practical results obtained by the author provide the required and additional quality indicators, increase the physical and mechanical properties of fine-grained mortars, increase productivity. Theoretically substantiated and experimentally confirmed the effectiveness of the joint use of fine fillers, superplasticizer S-3 or Melflux, the high activity of metakaolin and wollastonite as a part of the binder in the fine-grained mixture and concrete. The architectural pattern of the decision support system for analyzing the properties of fine-grained multifunctional concrete has been developed.
