Abstract: Cinder is a waste material obtained from steel manufacturing units. Cinder is the material partly fused or sintered arising from the combustion of coal and used in certain places where natural aggregate is not available or costly or recycling of the industrial wastes is aimed at or where the dead weight of the structure is to be reduced. The unit weight of the cinder concrete varies from 1980-2000 kg/m³ and it is less than that of conventional aggregate concrete. Light weight aggregate concrete is widely used in the construction industry.
