Title (EN) A CEMENTITIOUS MIXTURE CONTAINING HIGH POZZOLAN CEMENT REPLACEMENT AND COMPATIBILIZING ADMIXTURES THEREFOR
(FR) MELANGE A BASE DE CIMENT CONTENANT UN CIMENT DE REMPLACEMENT A HAUTE TENEUR EN POUZZOLANES ET DES ADJUVANTS COMPATIBLES
Abstract:
(EN) A cementitious mixture comprises a hydraulic cement; greater than about 10 % by weight of a pozzolanic cement replacement selected from fly ash, slag, natural pozzolans, and mixtures thereof, based on the weight of said hydraulic cement and cement replacement; and a compatibilizing admixture, wherein the compatibilizing admixture comprises a compatibilizing polycarboxylate polymer dispersant capable of acting as a water reducer, in combination with an accelerator.
(FR) L'invention porte sur un mélange à base de ciment comprenant un ciment hydraulique; environ plus de 10 % en poids d'un ciment de remplacement pouzzolanique sélectionné parmi la cendre volante, le laitier, les pouzzolanes naturels et des mélanges de ceux-ci, sur la base du poids du ciment hydraulique et du ciment de remplacement; et un adjuvant compatible comprenant un dispersant polymère de polycarboxylate compatible pouvant avoir la fonction de réducteur d'eau, en combinaison avec un accélérateur.
