A mixture of two kinds of ashes from municipal solid waste incineration (MSWIA) was used for synthesising new low-energy-belite cements in the range of temperatures from 700°C to 1000°C. The new cement process presents important environmental advantages, for one side, a dramatic reduction of CO2 emission versus that produced during the traditional manufacture of Portland cement, and for other, the employment of a residue as secondary raw material. Besides, the temperature of synthesis is strongly reduced in comparison to that of traditional belite cement manufacture. In this paper, the influence of several pre-treatment of MSWIA, on the hydraulic reactivity of cements are explored. The cemented phases were characterised by X-ray diffraction (XRD) and infrared spectroscopy (IR), and its hydraulic reactivity by the combined water content, which was evaluated from thermogravimetry TG) analysis.
