Composition and properties of foam glass crystal materials from compound of broken glass and high calcium slag (rus)
Abstract
The aim of this work is to decrease the consumption of broken glass shortage for obtaining heat insulation materials on its base. The results of research of composition and properties of foam glass crystal materials from compounds of broken glass and high calcium slag obtained in burning of brown coal in Kansk-Achinsk field are shown.It is stated that compounds from mixture of broken glass and high calcium slag in quantity of 30-40% granulated with 30% of liquid glass of density 1400 kg/m3 after burning pending 3 hours with endurance 20 minutes at 800°C provide the production of granulated and modular foam crystal materials. Bulk density of granulated materials is 180-200 kg/m3, compressive strength in cylinder is 1,0-1,1 MPa. Average density of modular materials is 320-400 kg/m3, compressive strength is 4,1-5,3 MPa.
