Title: High Calcium Coal Fly Ash as Raw Material for Synthesizing New Low-Energy Cements
Author(s): S. Goni, A. Guerrero, M. P. Lorenzo, A. Moragues, I. Campillo,
and J. S. Dolado
Publication: Special Publication
Appears on pages(s): 381-394
Keywords: high calcium fly ash; hydrothermal-calcination; low-energy belite cement
Abstract:Studies on the viability of high calcium fly ash from coal combustion are being conducted in our laboratory to produce a new kind of low-energy cement. The process presents important environmental advantages, such as a reduction of CO2 emission compared to that produced by the conventional technology of portland cement manufacture. Furthermore, the processing temperature is also considerably reduced. The low-energy cement shows potential for good hydraulic activity for application in construction. The changes of fly ash composition were followed by X-Ray Diffraction (XRD), FT Infrared (FTIR) spectroscopy and BET surface area analysis.
