Abstract

Agent superfluidifiant pour mortier ou béton, caractérisé en ce qu'il comprend un polysaccharide alkylsulfoné ayant un degreé de polymérisation pouvant atteindre 100 et un degré de sulfonation compris entre 0,2 et 3,0 ; il s'agit dans ce cas, du procédé de préparation de l'amidon alkylsulfoné soluble dans l'eau. Cet agent permet une augmentation de l'aptitude à l'écoulement d'un mélange de mortier ou de béton contenant un liant de ciment hydraulique.Superfluidifying agent for mortar or concrete, characterized in that it comprises an alkylsulfonated polysaccharide having a degree of polymerization which can reach 100 and a degree of sulfonation of between 0.2 and 3.0; in this case, it is the process for preparing water-soluble alkylsulfonated starch. This agent allows an increase in the flowability of a mortar or concrete mixture containing a hydraulic cement binder.
