Mineralogy of western (US) fly ash
Journal Article
·
· Cem. Concr. Res.; (United States)
Twenty-six fly ash specimens from N. Dakota, Wyoming and Montana lignite and sub-bituminous coals have been studied by X-ray diffraction. Chemically these western fly ashes are characterised by higher CaO + MgO + SO/sub 3/ contents and lower Al/sub 2/O/sub 3/ + SiO/sub 2/ contents than eastern bituminous fly ashes. The western fly ashes have greater proportions of crystalline materials, the characteristic phase being quartz, lime periclase, anhydrite, ferrite spinel, tricalcium aluminate, merwinite and melilite.
