IMMT develops technology for making bricks and blocks from mining wastes without firing

The Institute of Minerals and Materials Technology has developed a ‘geo-polymer’ technology for effective utilization of different matrials and waste resources such as fly ash, bottom ash, red mud, crushed dust, slags etc to make bricks and blocks, without firing.  

The approach adopts non-fired green route and 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.  

It is an Alkali activated and CO2 negative green process, high volume fly ash utilization including other industrial and mining wastes. Using this process, you can make 100,000 bricks a day.  

Rs. 30, 00,000/- investment for production capacity of 10,000 fly ash bricks/day. Production cost @ Rs. 3.00 per brick. These bricks have a compressive strength of class 7.5 and above.
