Abstract
The article provides information on industrial waste generation at enterprises of the Samara region, suitable for use as raw materials components of such heat-resistant composites as solutions, concretes, gun mixes, coatings. The research indicates rational ways of some heat-resistant binders application for utilization of mineral high-melting and heat-resistant industrial wastes. It proves that the enrichment of certain types of industrial waste, i.e. bringing the chemical composition of their components to the required state, allowed to expand the raw material base for the synthesis of heat-resistant binders and concrete in general. The use of sludge waste in the processes of synthesizing liquid phosphate binders allowed to obtain such effective binders as aluminophosphates and aluminocalciumphosphates. The research proves that application of technogenic wastes of non-ferrous metallurgy enterprises allows to receive heat-resistant materials solutions, concretes, coatings, gun mixes which characteristics are similar to their industrial analogues.
Highlights
On the territory of Samara region, not a dozen of quarries for nonmetallic raw materials extraction are functioning.In the region, oil and gas production is highly developed to provide local industry and energy complex with fuel
As there is a great number of local raw material available in Samara region, machine building, chemistry and petrochemistry, construction and construction materials industry, non-ferrous metallurgy and other branches of industry have greatly developed
Conditions
Summary
On the territory of Samara region, not a dozen of quarries for nonmetallic raw materials extraction (limestone, dolomite, gypsum stone, clay raw materials, sand and gravel mixture and others) are functioning.In the region, oil and gas production is highly developed to provide local industry and energy complex with fuel. One of the important problems is the production of materials with high physico-thermal properties for linings of thermal generating units operating in complex physico-chemical conditions Such fired products are quite suitable as fine additives and heat-resistant concrete heat-resistant aggregates
