Bricks from Industrial Wastes

Recently I visited CSIR technofest 2010 showcased by Council of Scientific & Industrial Research, New Delhi, at India International Trade Fair in New Delhi, the Capital of India. In this technofest, I have seen a technology "Bricks from Industrial Wastes" which was developed by CBRI (Central Building Research Institute), Roorkee under the aegis of CSIR, New Delhi, India.

Generally we know the bricks will be used in building industry. In this technology, bricks are making from plastic clay, fly ash from industries like thermal electricity or other industries and coal. This technology is cost effective and affordable.

Clay fly ash bricks and fly ash bricks will make from improved brick technologies. Bricks are making from inferior soils and agro industrial wastes. Bulk utilization of fly ash is for wasteland development and agriculture. CBRI Technology is for pollution control in brick kilns.

Energy/coal can be saved in firing upto 30% as compared to traditionally clay bricks. Waste utilization helps in disposable of waste (flyash) which poses a serious threat to environment and ecology. Know-how has already been transferred to several parties on sponsored/consultancy basis. Technology is already in production.

Estimated investment for a plant of 30,000 bricks per day capacity for manual process is Ra.15 lakhs and semi mechanized process is Rs.75 lakhs. Process know-how, raw materials specifications, process demonstration, training at site and laboratory will be given by CBRI, Roorkee.

Fly ash bricks have manyadvantages

-Fly ash bricks have more compressive strengththan conventional clay bricks

-More resistant to salinity and water than conventional bricks

-More lighter than conventional bricks

-Uniform in shape & size and more durable as strength increases with passage of time

-Less mortar consumption in masonry & saving in plastering cost. This reduces the building construction cost.
