Abstract
An equation for calculating the cement content in concretes made with aluminous cement is proposed, based on determining the Fe2O3 content of the concrete, assuming that the proportions of this oxide, as provided by the manufacturing company, throughout the production process are very stable. The values are corrected according to the Fe2O3 content of the aggregates. The Fe content is determined by x-ray fluorescence analysis (XRF).
Resume
On propose une équation pour calculer la quantité de ciment dans les bétons de ciment alumineux fondu. La méthode calcule la teneur en Fe2O3 du béton, attendu que les concentrations de cet oxide sont très constants pour le ciment alumineux. Ou décompte le taux de Fe2O3 des granulats. Pour l'analyse du Fe on a appliqué la fluorescence x. *** DIRECT SUPPORT *** A00G7067 00003
