Abstract
The influence of the synthesis temperature on the hydration reaction of new cements obtained from municipal solid waste incineration fly ash (MSWIFA), as a secondary raw material, is discussed in this work. Cements were synthesized in a range of temperature between 700 degrees C and 1400 degrees C from MSWIFA, which was previously activated by hydrothermal treatment at 200 degrees C and 1.24 MPa. The evolution of cemented phases with the heating temperature was followed by X-ray diffraction (XRD) and infrared spectrometry (IR). The results were compared with those obtained by heating the starting fly ash without hydrothermal treatment. The degree of hydration was semi-quantitatively evaluated by XRD, during a period of 28 days, in cements obtained at low temperatures (700 degrees C, 800 degrees C, 900 degrees C, 1000 degrees C and 1100 degrees C).
