Increase of physical and mechanical parameters of arbolite-concrete composites by deep impregnation with liquid sulfur

Abstract

The article deals with the influence of molten liquid sulfur on the physical and mechanical properties of porous arbolite concrete composites. For the manufacture of arbolite-concrete composites we used porous waste corn cob crushed with sizes from 10 to 40 mm. To compare the results of research we also adopted more dense waste vegetation crushed walnut shells with sizes from 10 to 20mm.To conduct the study adopted the method of complete impregnation of arbolitobetonnyh samples liquid molten sulfur. As impregnation, material used sulfur - waste oil production in Kazakhstan. The results of the study found that with an increase in the composition of arbolite concrete composites content of cellulose organic aggregates, there is a significant increase in compressive strength and average density of lightweight concrete depending on the duration of impregnation. We have revealed that physical and mechanical properties and corrosion resistance of impregnated arbolite concrete samples are very high and these data prove that they can be recommended for use in underground and engineering structures.
