Characterization of fly ash for potential utilization in green concrete

Coal-based thermal power plants are the residue material of the combustion of FA (Fly Ash). The use of FA has become an attractive alternative to disposals by raising the consciousness of the environment. The present study aims to examine the prospective use of FA in concrete and building applications, the physical, chemical, mineral and thermal properties of FA. FA obtained at the Rajiv Gandhi thermal plant, Hisar, Haryana, India, Electrostatic precipitations for experimental purposes. The FA sample is characterized as being mostly enriched in silicon; alumina and iron oxides fall into the F-type FA group. In the ash sample, Quartz and Mullite are the main mineral crystalline phases. Distinguishing thermal examination of the FA sample reveals degradation from 400 degrees C to 700 degrees C in a particular stage. The absorbed humidity and light volatility is removed in the sample during initial area. The findings of the characterization show that FA has the ability to replace the principal components of concrete like sand and to improve strength. The effects on the environment and economics of disposing FA will be reduced by establishing new opportunities for further use. Copyright (c) 2021 Elsevier Ltd. All rights reserved.
