Performance of Fly Ash and Stone Dust Blended Concrete in Acidic Environment

Alok Verma, Anıl Kumar Sahu, Mukesh Shukla


Large scale housing construction activities require a huge amount of resources. Out of the total cost in a construction project the component of material cost has a major share. Therefore, the need of the hour is the replacement of costly and scarce conventional building materials by innovative, cost effective and environmental friendly alternatives. Fly ash and stone dust, generated as waste products in coal based thermal power plants and stone crusher industry respectively have been found appropriate for this purpose. The objective of this study was to investigate the performance of concrete mixes blended with fly ash and stone dust in chemically aggressive environmental conditions. The results indicate that a judicious selection of these waste products as ingredients in concrete shall further enhance benefits under aggressive environmental conditions of exposure.
