Pond Ash

Pond ash, a byproduct from coal-fired thermal power plants, represents a significant category of thermal power plant waste. This material, often wet disposed in ash ponds, consists of relatively coarse particles compared to fly ash. Researchers are interested in pond ash due to its unique geotechnical properties, including compressibility and shear strength, which are critical for evaluating its suitability in various applications. Understanding the leaching potential of pond ash is also paramount for environmental impact assessments and ensuring sustainable development. While it exhibits pozzolanic activity, potentially making it useful as a construction material, further studies on its performance in concrete and as an aggregate are essential. Its potential as a soil amendment and its behavior in landfill and embankment constructions are also key areas of investigation. Characterizing the chemical composition and particle size of pond ash is fundamental for any research aiming at its effective waste utilization and recycling. Therefore, pond ash serves as a valuable research material for diverse studies across engineering and environmental sciences.
