Synthesis of belite cement clinker of high hydraulic reactivity / Larbi Kacimi in Cement and concrete research, Vol. 39 N° 7 (Juillet 2009) 

Public ISBD [article]  in Cement and concrete research > Vol. 39 N° 7 (Juillet 2009) . - pp. 559–565 Titre : Synthesis of belite cement clinker of high hydraulic reactivity Type de document : texte imprimé Auteurs : Larbi Kacimi, Auteur ; Angélique Simon-Masseron, Auteur ; Souria Salem, Auteur Année de publication : 2009 Article en page(s) : pp. 559–565 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Belite;  Clinker;  Reactivity;  Mineralizer;  Clinkerization Résumé : This study is concerned with the increase of the cooling rate of belite clinker, by using the water quenching for the chemical stabilization of reactive belite, which improves the hydraulic properties of this clinker. The addition of adequate mineralizers, as NaF and Fe2O3, contributes to the improvement of the clinker properties obtained at low burning temperature. X-ray fluorescence spectroscopy, X-ray diffraction analysis and optical microscopy were used to determine the chemical and mineralogical compositions of this clinker. The samples were analyzed by means of a scanning electronic microscope connected with an energy-dispersive X-ray spectrometer to detect the composition of the belite phase and its morphology. Physical and mechanical properties of this clinker cement were determined. The results show that the belite clinker obtained at 1150 °C, with lime saturation factor 0.67, is characterized by a great hydraulic reactivity, similar to that of the ordinary alite clinker. The addition of 2% of NaF and the water quenching improved the chemical, mineralogical and structural properties, while improving the cement hydraulic properties.
