Public ISBD [article]  inCement and concrete research > Vol. 39 N° 11 (Novembre 2009) . - pp. 1105–1109 Titre : Cement content determination through selective stain in hardened concrete Type de document : texte imprimé Auteurs : Lucía Linares, Auteur ; López Atalaya, Auteur ; Servando Chinchón, Auteur Année de publication : 2010 Article en page(s) : pp. 1105–1109 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Concrete  Cement paste  Image analysis  Coloured compounds Résumé : A cement quantification method has been developed in Ø 15 × 30 cm concrete specimens applying selective stain. A tannic acid–tartaric acid solution was used to stain the cement paste. This paper explains the procedure to determine the quantity of cement in the samples: the reagents utilised for the stain, preparation, cutting and stain of the specimens, the capture and treatment of images of the stained samples, and the preparation of the calibration curves. Next, we assess the accuracy of this method and include the resolution of a practical case in which a comparison is drawn between the values obtained through the application of this method and those obtained using a ‘reference’ method.
