The object of study is the process that occur during the structure formation of cellular glass, modified by fly ash, which allow to obtainpoorly conductingthermal insulating materials.The aim of the thesis isresearch and development of modified thermal insulating materials based on foam glass.Research methods: while studying mineral phase composition and structure of the samplesx-ray method was used as well asdifferential thermal and electron-microscopic analysis; components' optimization was carried out using a mathematical modeling; study of structural, physical and performance properties were carried out by standard methods, according to DSTU.Theoretical and practical results: developed understanding of the mechanism of impact of modifier on the structure formation of the thermal insulating material based on foam glass, it is proved that in the process of heating the fly ash of thermal power stations its inorganic component is softening at the temperature of heat treatment which is 50 °C lower than the inorganic component of cullet or quenched cullet, at the same timethe burnout of carbon in the particles of fly ashtakes place.Optimization of the gassing process and melt viscosityallowed to obtain more microporous structure of low density and high strength;manufacturing technology of a modified thermal insulating material based on foam glass was improved, there is no post production of quenched culletand there is a measuring hopper for the modifier which allows to reduce the cost of material.Scientific novelty: by addingtechnogenic raw materials (fly ash) with a specific chemical composition and applying cullet,a combination of chemical components was obtained that allowed to get an eutecticat a lower temperature, i.e. softening is not at 870 °C, but at 820 °C.At this temperature were obtained such rheological properties as the maximum shear stress and viscosity, providing microscopic pores, and due to this, reduction of thermal conductivity and gain in strength of the received material; microporosity was achieved due to the fact that in the particles of fly ash there are both eutectic composition, and carbon, which burns and provides the gassing.Degree of implementation: the research results have been implemented in developed technical specifications TU Ukraine. 2.7-26.1-00034045-001:2006 "Blocks made of porous thermal isolating material", and found application in the insulation of a private residence inDnipropetrovsk; economic effect, by reducing the cost of the modified foam, compared to the unmodified counterpart, is 393,30 UAH / m3.Field of application: industrial and civil construction, transport, process equipment, and so on; in the development of regulatory and guidance documents in the field of energy-efficient complex reconstruction of residential development.
