Engineering Properties of Calaca Batangas Bottom Ash

Oscar Victor M. Antonio, Jr., Mark Albert H. Zarco


The coal-fired power plant of the National Power Corporation (NAPOCOR) in Calaca, Batangas emits an estimated 62.62 tons of coal combustion products (CCPs) per hour on a 24-hour daily basis. Like other coal power plants, the continuous disposal of coal combustions products such as fly ash, bottom ash and boiler slag in landfills or surface impounds creates environmental problems to people living in the neighboring areas. The accumulation of these by products poses a significant environmental risk at the rate these byproducts are being generated. The objective of this study is to determine the engineering properties of Calaca, Batangas bottom ash. These engineering properties can be used to find and assess the possible ways of utilizing and maximizing the potential of such byproduct in a manner that is both environmentally friendly as well as economically viable. Apart from solving the environmental problems related to its disposal, the use of coal combustion byproduct also saves natural resources and energy because it makes waste materials useful through recycling. This study focuses on the determination of the chemical composition, as well as physical and mechanical properties of bottom ash.

Keywords: Coal Combustion Byproducts, Bottom ash.
