Optimization of One-Stage Technology of Granulated Foam Glass on the Basis of Low-Temperature Synthesis of Glass Phase

Basic principles of the development and optimization of foam-glass and foam glass crystalline materials by the method of low-temperature synthesis of a glass phase on the basis of siliceous opal-crystobalite rocks are considered. A brief comparative review of basic technologies of granulated foam glass manufacturing is presented. Total expenditure for alkali-containing raw components as well as total technological energy consumption for foaming and drying are offered as criteria of the optimality of foam glass one stage technologies. The description and substantiation of the developed optimized one-stage technology of granulated foam glass based on producing raw granules (batch) by means of granulating the fine ground siliceous component with the sodium-containing binding mortar on the basis of silicates and other water-soluble sodium salts are given. Main properties of obtained granulated foam materials and technical-economical advantages of the developed technology are presented.
