Abstract

A technology for the utilization of technogenic waste from the oil and gas industrial complex (sulfur) and ash and slag waste from the combined heat and power plant for the manufacture of thermal insulation material with high strength and performance properties has been developed. A technological scheme is proposed. The optimal parameters and composition of the obtained thermal insulation materials have been determined. A numerical method for determining the thermal conductivity coefficient of a building product based on the calculation of a stationary temperature field is considered. The dependence of the thermal conductivity coefficient of a block on the value of the thermal conductivity coefficients of the base material and filler is obtained. The efficiency of block insulation has been determined. This method can be used at the design stage of wall products, varying their overall dimensions, the geometry of the slots and also using various thermal insulating materials as a void filler.

Highlights

The improvement and development of construction materials manufacturing and the increase in their economic productivity in the modern world will largely be formed by the expediency of using huge resources, attracting waste from various areas of the industrial field [1,2]
The studies used compositions that were prepared by mixing the initial components in the specified ratios
After the resulting mixtures were filled in a form of 20×20×60 mm, it was found that the optimal ratio in compositions – cement: filler is 1:3

Summary

Introduction

The improvement and development of construction materials manufacturing and the increase in their economic productivity in the modern world will largely be formed by the expediency of using huge resources, attracting waste from various areas of the industrial field [1,2]. Waste heat energy occupies one of the first places in volume, and in connection with the infinite improvement of technologies, the volume of industrial ash and slag waste (ASW) is increasing. According to this reason, it can be assumed that ash and slag dumps for the degree of unfavorable environmental impact will occupy one of the main places among industries.
