摘 要：In recent years,circulating fluidized bed combustion fly ash（CFA） is used as a raw material for geopolymer synthesis.Hydrogen peroxide was employed as a foaming agent to prepare CFA-based foam geopolymer.The particle distribution,mineral composition,and chemical composition of CFA were examined firstly.Geopolymerization products were characterized by mechanical testing,scanning electron microscopy（SEM）,X-ray diffraction（XRD）,and X-ray fluorescence（XRF）.The CFA-based foam geopolymer was successfully fabricated with different contents of hydrogen peroxide and exhibited uncompleted alkali reaction and reasonable strength with relative low atomic ratios of Si/Al and Si/Na.Type-C CFA in this research could be recycled as an alternative source material for geopolymer production.
