Sulfur is produced in large quantities in gas processing plants and its rapid availability requires a comprehensive study of this substance and its use in various sectors of the national economy by turning it into environmentally friendly compounds. Purpose of work. Production of sulfur concrete based on melamine and modified sulfur and study of its physical and mechanical properties. Methodology. The microstructure of modified sulfur concretes was studied by SEM and IR spectroscopic methods, thermal characteristics were determined by differential thermogravimetric met hods in the DT-60 device. Originality. A new type of sulfur concrete was obtained based on melamine and modified sulfur; the physical and mechanical properties of the obtained concrete were determined to have high deformation stability and adhesion properties. Findings. Due to the unique structure of the melamine substance and the presence of active functional groups, the formation of a copolymer with modified sulfur showed that it participates as the main binding agent in the production of sulfur concrete.enMelamine, sulfur concrete, modification, copolymerArticle
