Multicomponent concretes with local raw materials and organic mineral additives

Abstract

The paper presents the results of studying dense structure concrete containing highly dispersed aleuropelite rocks; amorphous silica-containing, plasticizing and water-repelling additives. The use of natural raw materials and modifying additives in rather low dosage ranges has been proved rational for mass construction concentrated on the use of B30-50 class concretes. It has been established that concrete structure forming, its physical and technical characteristics and durability are ensured by the compositions without involving additional grinding operations and activating the mineral component in the technological process. The proposed technical solutions serve as the basis for the production of a whole class of micro-concrete that is efficient in terms of technical and economic indicators.
