Brief Description

Description :

A mineral polymerization technology has been developed for effective utilization of different materials and waste resources like, fly and bottom ash, red mud, crusher dust, slag etc. to address the issues of environmental pollution. The approach adopts non-fired green route and has the potential in making products like building bricks, blocks, tiles etc. for construction industry. The process feature involves a chemical transformation of oxides of iron, alumina, Lime and silica bearing mineral constituents of the materials in formation of hydrous silicate structures which follows a pathway of gel formation and solidification where the product gains binding strength.
