Recycling
Improving the performance of the gypsum binder is possible by strengthening the gypsum matrix. The increase in strength is ensured by the introduction of a complex of mineral and chemical additives. The use of waste as components of such a complex solves a set of problems. The market is saturated with competitive and high-quality materials. Designed materials meet modern requirements. In addition, the problems of waste disposal, freeing up space, environmental protection and reducing the resource intensity of production are being solved.
The purpose of the work is to obtain energy- and resource-saving compositions of gypsum dry building mixtures with improved physical and mechanical characteristics through the use of modifiers from the resources of the local raw material base. The addition of basalt waste and hydro-removal ash to the gypsum binder as part of a complex of mineral and chemical additives ensures the formation of a hardened modified gypsum stone. During the research, regularities were established for the influence of the components of the additive complex on the properties of the gypsum binder. Optimal ratios between gypsum binder and modifiers have been selected. The microstructure of the modified gypsum stone has been studied. The positive effect of the complex on the structure of gypsum has been proven.
