Effects of Different Types of Power Plant Ashes on Foamability and Structure of Al Foams

Abstract:

Addition of power plant ash particles, classified as cenosphere and precipitator fly ashes, and bottom ash, to Al foams resulted in different foamabilities and foam structures. These distinctions arise from a difference in physical and chemical characteristics of ash particles. The cenosphere fly ash is hollow, whilst the precipitator fly ash is dense. The bottom ash is also dense with irregular shape. The major chemical constituents of these ashes are SiO₂, CaO, Al₂O₃ and Fe₂O₃. It is found that the improvement in foam expansion and structure is obtained from the addition of precipitator fly ash or bottom ash particles. The addition of cenosphere fly ash, however, leads to a decrease in foamability and non-uniform foam structure.
