Abstract

L'invention concerne un adjuvant permettant de diminuer la teneur en eau d'un mélange de béton. L'adjuvant comprend une solution alcaline d'une lignine sous forme sulfométhylolatée. La lignine sulfométhylolatée contenue dans l'adjuvant peut également être réticulée par un agent de réticulation. L'adjuvant comprend en outre un entraîneur d'air. L'invention concerne également des compositions de ciment originales contenant ledit adjuvant.
