PHYSICO-MECHANICAL AND THERMOPHYSICAL PROPERTIES OF FOAM- GLASS CERAMICS BASED ON SILICA ROCK
Abstrak
Obtaining the foam-glass ceramic building materials bypassing the process of high-temperature glass melting and the use of local rocks as raw materials, which can significantly reduce the cost of the final product, is an urgent task of modern building materials science. The aim of this work is to study the physical, mechanical and thermal properties of foam- glass ceramic building materials obtained by one heating of the mixture consisting of silica-containing rock (tripoli) and soda ash. The developed heat-insulating building materials have an average density of 200 to 600 kg/m3, compressive strength of 1.2 to 9.8 MPa, thermal conductivity of 0.053 to 0.065 W/m °C. Studies establishes a rational ratio of components in the composition of foam glass ceramics based on silica rock. In the production of foam materials, the heating rate of the charge should vary from 3 to 4.5 ° C / min, and the maximum heating temperature from 800 to 850 ° C. The developed material will expand the range of thermal insulation building materials and can be used in the construction of industrial and civil facilities, nuclear power plants, in the gas and oil industry.
