The process of coal combustion results in coal ash, 80% of which is very fine in nature & is thus
known as fly ash. Presently, in India, about 120 coal based thermal power plants are producing
about 90-120 million tons of fly ash every year. With increase in demand of power energy, more
and more thermal power plants are expected to commission in near future and it is expected that
fly ash generation will be 225 million tons by 2017. Disposal of fly ash requires large quantity of
land, water and energy and its fine particles, if not disposed properly, by virtue of their
weightless, can become air born and adversely affect the entire Environment. These earth
elements primarily consist of silica, alumina & iron etc. and its physicochemical parameters are
closely resembles with volcanic ash, natural soil etc. These properties, therefore, makes it suitable
for use in ceramic industries and helps in saving the environment and resources.
