Maksimenko A. Dry building mixtures for floors on the basis of magnesium compositions

The object of research - hydration process of compositions based on magnesium-bishofit binding, sulfate and siliceous aggregates anthropogenic origin, and polymer additives. The purpose - determination of optimum parameters of the burning magnesium cement, magnesia bishofit development matrix and its modification for the device waterproof floor elements with high physical-mechanical properties. Research methods: Research magnesia stone made using modern methods of physicochemical analysis: X-ray diffraction, differential thermal and spectral microscopy. Determination of physical and mechanical properties carried out using existing techniques in accordance with existing regulations. Theoretical and practical results: theoretically justified and developed firing medium active magnesia cement ratio to form an ideal MgO/MgCl2 oxide hydrochloride magnesium content and physico-chemical aspects of composition based on magnesium-bishofit binder. Scientific novelty: first developed physicochemical aspects of composition based on the obtained average active magnesia cement , mixing at the optimum ratio of magnesia powder magnesium chloride solution , which simultaneously reacts with silica- sulfate additives , talc , super plasticizers and form, except oxide hydrochloride solid solutions of magnesium dehydrate calcium hydrated magnesium - sepiolite and low-alkaline hydro silicates calcium , which reduces deformation and increase the strength and water resistance of the structure of the stone. The degree of implementation: developed compositions and technological scheme of dry mortars for floor elements on the basis of magnesium-bishofit binding using man-made products. Pilot tests conducted on the enterprise " Balovsky Reinforced Concrete Plant" in 2012 у. The economic effect is 106.14 grn/m2. The sphere of application: the production of building materials and construction.
