Properties of Industrial Slag as Fine Aggregate in Concrete
AbstractThe main objective of this paper is to use the industrial waste such as bottom ash and Weld Slag (WS) as the partial replacement for fine aggregates in concrete. This paper presents the chemical analysis and strength properties of industrial solid waste such as bottom ash, weld slag 1 (WS 1) and weld slag 2 (WS 2). Their chemical compositions were identified by X-ray powder diffraction (XRD) analysis. The qualitative and quantitative elemental analysis of the bottom ash and weld slag was recognized by energy dispersive X-ray analysis and their morphology were studied by Scanning Electron Microscope (SEM). The compressive strength of concrete with 10% replacement of fine aggregate to the industrial waste shows higher strength than the normal concrete and hence this industrial waste can be used as fine aggregate in concrete.
