An Overview Study of Fly Ash

Abstract

—India is a vast country with huge population. The demand is not only on industrialization and housing but
also equally on infrastructure where interconnecting the whole nation through road network is one of the important
ongoing activities. If the interlinking of rivers also comes true this is another dimension of development. All these
projects bring in lot of pressure on the construction material, with major thrust on bricks and concrete, because of their
voluminous consumption. India is bestowed to generate more than 150 million tons of industrial by products annually
which can best be utilized in bricks cement and concrete. Fly ash is the major by product and is available in almost all
parts of the nation. Hence solving the fly ash problem is tantamount to solving the major share of the issue. In this
background authors discuss the use of fly ash in bricks and concrete with special emphasis on FaL‐ G technology. The
indicators for sustainable development are also discussed thereupon. In view of its voluminous availability bituminous
coal is used in about 95% of coal‐ based thermal power generation, thus generating major lot of fly ash as ASTM Class
F. This review paper present the classification of fly ash uses in various parts of construction and how to help in
environment protection by using fly ash.
