Sem-eds and TG-DT analysis on coal-bagasse ash and clay-perlite aggregates

Abstract

An industrial waste removal process plays main roles in all production industries, in this paper discussed about the sugar industry waste i.e. bagasse used as fuel along with coal in thermal power plant. After combustion of Coal-Bagasse, it produces bulk amount of ash and clay from the local fire brick manufacturers and expanded perlite from the thermal insulation powders suppliers. Coal-Bagasse ash, clay and perlite were performed to brick manufacturing. These three constituents with different ratios (10:5:1) on weight basis, mix properly with little addition of water for required plasticity. This mixture poured into moulds for required shape of sample (120mmx60mmx50mm) according to the laboratory requirements. Prepared samples were dried in atmosphere until the removal of wet content in samples. For final curing, dried samples heated in electrical furnace, at different temperature ranges. Scanning Electron Microscope with Energy Dispersive Spectrum (SEM-EDS) was performed to study the microstructures and chemical composition (on mass & weight basis) of samples, Thermo gravimetric-Differential Thermal Analysis (TG-DTA) to study the variation in mass of samples at different temperatures with respective time. The result shown maximum weight loss obtained at more quantity of coal, high compressive strength and low thermal conductivity at more amount of clay-bagasse ash.
