Development of Multicomponent Binders Using Fine Powders

Abstract

The paper discusses the issues associated with the development of multi-component binders and high-quality concrete on their basis. The basis for the preparation of such binders is the use of finely divided mineral additives of natural and man-made origin. Particular attention is paid to the aggregate, the strength of coarse aggregate should be at least 20% higher than the strength of concrete, and the maximum particle size should not exceed 8–20 mm. To date, considerable experience has been gained in the production of multicomponent binders, and the results of the research carried out in this direction have shown that the raw material potential of the republic allows obtain high-quality concrete of class B 30-40. As if to expand the geography of natural resources regions of the North Caucasus Federal District, it is possible to obtain concrete of higher strength.
