The scientific achievements in the theory and practice of concrete production and application have been summarized. It has been demonstrated that the present-day level of scientific developments allows obtaining up-to-date modified concretes with high technological and service properties. Nevertheless, such concretes have not yet found wide application in the industry, and the existing raw-materials, production and regulatory-technical base are not ready for such concretes production. This, in its turn, results in the considerable cost increase of the existing general-purpose concretes and the unreasonable overconsumption of costly chemical admixtures. At the same time, there is a real opportunity of obtaining low-cost and efficient modifiers on the basis of chemical production waste, the implementation of which would expand the range of modifying the widely used general-purpose concretes without increasing their cost. The research findings of new highly-efficient plasticizing admixtures on the basis of chemical production waste have been presented. Their influence on the properties of concretes and concrete mixes has been studied. The experimental data demonstrate that at a certain ratio of superplasticizer with sulfo-groups and hydroxyl groups in a polyfunctional modifier (PFM) a synergistic effect is observed, caused by attractive interactions of molecules on the dispersed phase particles’ surface. This would allow considerably reducing not only the consumption of the expensive admixtures, but also the final cost of concrete. At present the leading role in construction and in housing and utilities infrastructure belongs to the application of up-to-date domestic materials and technologies. This is especially relevant nowadays, within the framework of import phaseout of materials and technologies.
