RAW MIXTURE FOR PRODUCING FOAM GLASS AND METHODS FOR PRODUCING SAID RAW MIXTURE, BATCH AND FOAM GLASS

Document Type and Number:

WIPO Patent Application WO/2005/049518

Kind Code:

A1

Abstract:

The invention relates to producing building materials exhibiting low heat-conduction and density values, in particular to production of a block foam glass from crushed glass. The inventive method makes it possible to obtain a high-quality foam glass in a low time- and energy-consuming manner by producing an initial raw mixture using an aqueous alkali solution of sodium and/or calcium in a quantity equal to or greater than 30-70 mass % and a powdered crushed glass of a random chemical composition in a quantity ranging from 26 to 65 mass %. The thus obtained dehydrated raw mixture is treated at a temperature of 450-550°C is broken into a powdered batch which is, afterwards heated to a foaming temperature ranging from 750 to 830°C.
