Fly ash is naturally cementations coal combustion by-product. A fine glass powder recovered from the gases of burning coal during the production of electricity is fly ash. The combustion of powdered coal in thermal power plants produces fly ash. Disposal of high amount of fly ash from thermal power plants absorb huge amount of water, energy and land area by ash ponds. Generation of large quantities of industrial waste is one of the most important ill effects of these global processes. Therefore, the problems related with their safe management and disposal has become a major challenge to environmentalists and scientists. Second related problem is the pressure on land, materials and resources to support the developmental activities, including infrastructure. This fly ash has several uses in construction industry like fill material in concrete, additives in road construction, brick making mosaic tile production etc. The paper focuses on the current utilization fly ash in construction industry.
