O. Assistant, Fergana Polytechnic Institute, Farg'ona, Uzbekistan Received 9 th Sep 2022, Accepted 19 th Oct 2022, Online 25 th Nov 2022 Abstract: This article highlights the degree to which the chemistry of foamed glass is dominated by silica compounds, its use in cement-based compositions, and the degree to which these types of corrosion have been studied for the first time. The article presents the results of a study of the state of production of a foam glass and the nomencla-ture of its products. It is shown that it is expedient to use the recycled glass obtained from the bottle battle, the defective glass and the double-glazed windows as a raw material for the production of the foam-glass. The re-quirements are formulated for glasses, which should have low viscosity values in the range of foaming tempera-tures. The features of the technology for the production of the foam glass aggregate at the specialized lines are outlined. The technology features are the composition of the charge and temperature conditions of burning. The mixture for the production of the foam glass aggregate consists of glass flour, organomineral blowing agent con-taining water and food glycerin, as distinct from the slab foam glass, where soot or coke is used as a blowing agent. The results confirm the effectiveness of the use of the foam glass aggregate as a soundproofing backfill for floors. Currently, about 70% of the foam glass aggregate is used for roofs and stylobates; the rest is used in landscape design, road construction, foundations and major repair. In the future, the areas of application of the foam glass aggregate can be significantly expanded in the direction of building systems, lightweight aggregates, etc., which involves in-depth studies of the properties of this material.

Foam glass crushed stone, produced on specialized lines, has a density of 120 to 200 kg/m3 and a grain size 40–60 mm [1,3]. Foam glass aggregate is covered with layers of 10–15 cm with layer-by-layer compaction. For the first time, the foam glass as a building material was mentioned by Academician I.I. Kitaygo- rodsky at the All-Union Conference on Standardization and Production of New Materials in Moscow in 1932. Soon, a technology was proposed in the USSR. Areas of application of foam glass were outlined [4–6]. In the 1930s, intensive work began and patents were obtained for the production of foam glass in
