High-Quality Modified Concretes with the Use of a Binder on the Basis of a Reaction-Active Mineral Component

Issues related to the development of high-quality concretes are considered. As a base of producing such concretes, the use of efficient chemical modifiers improving the rheological properties of concrete mixes and reaction-active fine mineral mineral components of natural and anthropogenic origin facilitating the improvement of their physical-mechanical characteristics. A special attention is paid to the filler: the strength of coarse filler must be higher than the concrete strength by not less than 20% and maximum filler size should not exceed 8–20 mm. At present, significant experience in production of high-quality concretes is accumulated and it is necessary to implement it in practice. Results of the study conducted show that the raw material potential of the Chechen Republic makes it possible to produce high-quality concretes of B 40 class, and if to expand the geography of North Caucasian Federal District it can be possible to produce concretes of more high strength.
