The Use of Self-Compacting Concrete Mixes in Construction Practice of the Republic of Bashkortostan

The growth of high-rise construction and the complexity of the forms of structures erected leads to the need to develop new types of concrete mixes and improve the technology of their laying. Now one of the innovative types of concrete is self-compacting concretes (SCC). Their advantage is that, due to their high mobility, they spread and completely fill the space in the formwork, thus reducing the permeability and increasing the durability of structures by achieving a high density of concrete. In order to study the possibility of obtaining self-compacting concrete of strength classes B25–B45 from raw materials of the Republic of Bashkortostan was conducted a set of experiments on the selection of compositions of self-compacting concrete mixes, determined their rheological and strength characteristics. Experimental data show the possibility of obtaining self-compacting heavy concretes based on local raw materials (the obtained data on strength, fluidity fully meet the normative values). Practically the possibility of using the developed compositions was confirmed by their application at several sites in Ufa.
