【 摘 要 】

Subject: the effectiveness of using compositions with the use of basalt fibers is proven, but the composition must be selected depending on the binder and additives chosen. Research objectives: we examine the possibility of waste recycling of basalt fiber production during manufacturing of modified gypsum composite material with improved characteristics. Materials and methods: as a raw material, a gypsum binder of Samara production was used. As a reinforcement additive, a disperse waste of basalt fiber production of Tver region was used. Studying characteristics of the gypsum binder and modified mixture, and also comparative analysis of these characteristics by average density, total porosity, strength in compression and flexure of the gypsum composite were carried out using standard techniques. Results: dependence of physical and mechanical properties of the modified gypsum material on the content of the basalt fiber additive is established. It was found that an increase in concentration of the additive requires an increased water content or additional use of plasticizer. Conclusions: modification of gypsum stone with a mineral basalt additive will increase the strength, density and durability of thin-walled gypsum products, and, consequently, the demand for products due to ensuring their high quality in transportation and installation.
