(FR) L'invention fournit un additif à ciment ayant pour matériau de base un végétal ligneux, ne mettant pas en œuvre de ligninesulfonate, et pouvant être obtenu à travers un processus au cours duquel les additifs ayant pour matériau de base une lignine, tels que dans l'art antérieur, sont peu nombreux. Plus précisément, l'invention concerne un additif à ciment comprenant une lignine. Cette lignine a pour composant principal une alcali-lignine obtenue avec un végétal ligneux pour matériau de base.
