Utilization of coal fly ash in concrete industry to protect the environment Bhatia Anita S.S. Jain Subodh P.G. Autonomous College, University of Rajasthan, Jaipur, India Online published on 8 May, 2017. Abstract Coal fly ash is an abundant industrial waste product, known to be a good pozzolanic material and has been used to increase the ultimate compressive strength and workability of fresh concrete/For this simple reason it is rapidly becoming a common ingredient in concrete all over the world-it is already present to some degree in half the concrete/The use of fly ash as a performance-enhancing ingredient in concrete is one of the most outstanding examples of industrial ecology-i.e., making effective use of waste resources, and ultimately eliminating the concept of waste altogether/Concrete is an environmental friendly material and the overall impact on the environment per ton of concrete is limited/The paper covers the aspect on how to choose a material for Construction industry/It presents the feasibility of the usage of by product materials like fly ash, query dust, marble powder/granules, plastic waste and recycled concrete and masonry as aggregates in concrete/The use of fly ash in concrete contributes the reduction of green house emissions with negative impacts on the economy/It has been observed that 0/9 tons of CO2 is produced per ton of cement production/Also, the composition of cement is 10% by weight in a cubic yard of concrete/To avoid the pollution and reuse the material, the present study is carried out/Thus, concrete is an excellent substituent of cement as it is cheaper, because it uses waste products, saving energy consumption in the production/The trend is clear, Fly Ash will soon be considered as a resource material and its potential will be fully exploited/Through development & application of technologies, Fly Ash has shifted from “Waste Material” category to “Resource Material” category/Thus fly ash management is a cause of concern for the future/ Top Keywords Fly ash, compressive, Eco-friendly, Construction material, efficient concrete.
