Use of waste in production of thermal insulating slabs

Abstract

The purpose of the article is to find the rational use of waste formed in the course of production of heat-insulating plates on the basis of foamed polyisocyanurate, together with gypsum binder. Some tests were carried out to determine the thermal conductivity and strength of the obtained material, the estimation of their characteristics, the analysis of efficiency and needs of the final product in the market of building materials is given. It was established that when gypsum binder and additives are used together the result is a material with the best initial indicators of heat insulation and strength. The results of research showed that at the optimum composition of the gypsum and additives the material is not inferior to the individual indicators of drywall and gypsum. Board which proves both its efficiency and its need for construction.
