Abstract

L'invention concerne une composition de liant activable par un alcali contenant (i) un liant choisi dans le groupe des laitiers de haut fourneau, de la fumée de silice, de l'argile calcinée et des pouzzolanes et (ii) du tanin soluble dans l'eau à une dose de tanin (ii) en référence au liant (i) de 0,1 à 4 % en poids. Le liant (i) peut contenir du ciment à un rapport de 10 % en poids ou moins. L'invention concerne en outre un mélange de matériaux de construction aqueux contenant la composition de liant et une structure de construction durcie obtenue à partir du mélange de matériaux de construction aqueux. En outre, l'invention concerne l'utilisation de tanin en tant que dispersant pour un composant liant dans une telle composition de liant activable.
