INVESTIGATION OF CHARACTERISTICS OF THE BUILDING PRODUCTS ON THE BASE OF TECHNOGENIC ANHYDRITE
In the article the research of manufacture of the building products on the base of technogenic anhydrite as a binder is proposed and conducted. The following components were added to the composition: basalt fibre, foamed expanded polystyrene. The samples of the existing popular building fit out sheets GKL (gypsum boards) and GVL (gypsum-fiber sheets) of the brand «Knauf» were investigated, which were taken by us as a sample. The density and the strength properties of the samples were examined. The optimal composition of the technogenic mixture corresponding to the prototype samples made of natural materials was specified. The strength and the density of the products made of optimal mixture makeup were determined. The conclusion was drawn that the anhydrite binder produced from the technogenic materials can replace the gypsum binder in the fit out building products GKL (gypsum boards) and GVL (gypsum-fiber sheets) so that the environmental pollution in the places of calcium sulphate waste accumulation will be eliminated and the costs of the building products will be lowered.
