Study of Properties of Coal Bottom Ash and Waste Foundry Sand and its Use in Concrete

Abstract

India produces abundant of industrial waste like bottom ash (CBA) and waste foundry sand (WFS) whose productive use or recycling and reuse is the best option available to reduce the threat caused by their disposal on environment. This research work aimed to find possibility of using both these waste materials in concrete for which study of characteristics of the materials is important. It is found that CBA needs to be processed before using in concrete. The results of Grounded CBA & WFS resemble within its permissible limit, and thus, these waste materials can be used as a substitute of cement and sand, respectively. Experiments are conducted on concrete containing CBA & WFS in the proportion of 10 and 6%, respectively. Through the experiment, we concluded that processed CBA & WFS can be partially replaced for cement and sand, respectively.
