Engineering characteristics of kaolin mixed with various percentages of bottom ash

Coal is one of the world's most important sources of energy, fuelling almost 40% of electricity worldwide. The burning of coal produces coal ash that mostly consists of fly ash and bottom ash. Bottom ash (normally recognized as coal combustion residues) has been categorized as solid waste (garb...
