Аннотация: The article represents the results of using industrial sulfur as an additive to a fluoroanhydrite based binder and the estimation of its influence on mechanical and physicochemical properties. Waste generated by human activities on an industrial scale, such as industrial sulfur and fluoroanhydrite, pose a serious environmental problem in terms of storage and disposal. Moreover, industrial sulfur and fluoroanhydrite have particular properties to form composite material with required properties. A number of studies have been carried out on using industrial waste as components of building materials, performance properties of the products obtained being improved and the functional use of the products being expanded. In order to study changes in the mechanical properties and physicochemical composition of material based on synthetic fluoroanhydrite, conventional testing methods accompanied by modern methods including scanning electron microscopy and X-ray analysis and infrared spectroscopy, were used. According to the obtained results compressive strength of composition modified with 10 % of thermoplastic additives was 35.77 MPa, water resistance was 0.68. This increase in mechanical properties is due to an interaction between chemically reactive polymorphic types of sulfur which are formed by transformation of α- type to β- and fluoroanhydrite binder. The results of the presented study prove the possibility of creating a building material, the composition of which is fully represented by industrial waste and the characteristics of which are not inferior to its analogues in terms of technical and economic properties.
