Strength and compressibility charactrisitcs of kaolin mixed with bottom ash
Coal is one of the world’s most important sources of energy, fuelling almost 40% of electricity worldwide. The burning of coal produced coal ash that mostly consists of Fly Ash and Bottom Ash. Bottom Ash (normally recognized as coal combustion residues from pulverized fuel power stations) has been c...
