Abstract

The widespread use of thermal insulation building materials on construction sites in the Republic of Belarus clearly demonstrates the high demand for this segment of products. However, today this type of building materials is mainly represented by gas silicate and expanded clay concrete blocks, as well as mineral wool and various kinds of foamed polymers. As an alternative, it is proposed to use non-autoclaved aerated concrete technology, which makes it possible to fill the cavities of removable and non-removable formwork of enclosing and partition building structures with expanded aerated concrete mixture and obtain ready-made insulating structures without the use of masonry work and the cost of adhesives for masonry block products. This technology additionally solves the issue of recycling of fine fractions of granite screenings produced by the Granit Company, Mikashevichi.
