Determination of thermal conductivity and thermal resistance of fire-resistant and heat-insulating wall materials made on the basis of industrial waste.

The article discusses the effectiveness of the use of aerated concrete products in the construction industry, the properties of thermal conductivity and heat resistance properties of aerated concrete in comparison with other building materials have positive indicators. The opinions of scientists on the influence of density, porosity and humidity on the properties of thermal conductivity and heat resistance of aerated concrete, which belongs to the class of cellular concrete, are explained. There are also opportunities for use in the production of building materials from waste, which always arise at enterprises producing asbestos products.The measurement of the asbestos fiber content in industrial waste of asbestos used in the aerated concrete sample was seen in the Altami MED microscope. The amount of oxides contained in the used industrial waste was determined using a modern X-ray fluorescence spectrometer of the ARL perform'x series.It is also explained that in the laboratory of the Jizzakh Polytechnic Institute, aerated concrete samples were prepared by adding various amounts of silica and asbestos as an addition to industrial waste. It was noted that experimental work was carried out to determine the coefficients of thermal resistance and thermal conductivity of equipment of the XND-2-3030C brand, which is available in an accredited laboratory of the Institute, the results of which meet the requirements of GOST.
