Critical Review on Types of Bricks Type 9: Flash Bricks

It is estimated that in INDIA 180 billion tons of common burnt clay bricks are consumed annually approximately 340 billion tons of clay about 5000 acres of top layer of soil dug out for bricks manufacture, soil erosion, emission from coal burning or fire woods which causes deforestation are the serious problems posed by brick industry.One the other side our country is highly dependent on the coal for generation of electricity, during the process the coal powder left as a residue which is quite harmful to the environment as well as living being and that waste residue is termed as “Fly ash”.Since fly ash is being accumulated as waste material in large quantity near thermal power plants and creating serious environmental pollution problems, its utilization as main raw material in the manufacture of bricks will not only create huge opportunities for its proper and useful disposal but also control environmental pollution to a greater extent in the surrounding areas of power plants For the construction works bricks are regarded as the most important material, so bricks made up of 100% fly ash has been introduced. So this paper deals with the manufacturing process and test of such bricks, the introduction of such bricks are termed as flash bricks whereas flash bricks can be extensively used in all building constructional activities similar to that of common burnt clay bricks. The flash bricks are comparatively lighter in weight and stronger than common clay bricks. Keywords - Flash Brick Process Of Manufacturing, Tests, Advantage
