Abstract
Power plant coal combustion residues (CCR) that consist of bottom ash and off-spec fly ash may be beneficially converted to value-added construction materials thereby reducing disposal costs and landfilled waste. Coal ashes have been investigated as sources of raw material for lightweight aggregates owing to their mineral properties, using well-known processes for agglomeration of fine particles (e.g., via sintering or autoclaving processes). Recent literature by Billen et al. [1]. Proposed converting coal bottom ash to spherical porous reactive aggregates (SPoRA) using a sintering process and fluxing agents that allow lowering the operating temperature of the rotary furnace used to produce the lightweight aggregates (LWAs).
