The article deals with the study of increasing the durability of arbolite concrete products by means of deep impregnation with sulfur from petrochemical waste. As the composition of arbolite-concrete composites includes various vegetable wastes (wood chips, crushed stalks of cane and cotton, corn cob wastes, crushed walnut shells, etc.) and it has low strength and has a small average density. For this reason, deep seasoned impregnation of molten liquid sulfur of samples of arbolite concrete composites should lead to an increase in physical and mechanical characteristics and durability of lightweight concrete and will also protect against the effects of aggressive external factors. The impregnation of porous arbolite-concrete composites is made by the contraction method, when the penetration of the impregnating liquid into the freshly molded arbolite-concrete mixture occurs due to the vacuum caused by physical and chemical processes of the cement binder dough. For making arbolite-concrete composites we used porous wastes of shredded corn cob with sizes ranging from 10 to 40 mm. To compare the results, we used denser wastes of crushed walnut shells with sizes from 10-20mm and crushed cotton stalks with sizes 10-25mm. For the study adopted the method of complete impregnation of arbolite concrete samples with liquid molten sulfur. As impregnation material sulfur-waste of oil refinery of Atyrau region of Kazakhstan was used. We have established that the physical and mechanical properties of impregnated arbolite concrete samples are very high and they can be recommended for use in underground and engineering structures.
