    摘要: A deep mix soil stabilization system comprises a hydraulic cement grout, and a soil dispersant comprising at least one of i) an acrylic acid polymer or copolymer, or a salt thereof, ii) an acrylic acid/sulfonic acid copolymer, or a salt thereof, iii) an acrylic acid/phosphonic acid copolymer or a salt thereof, and iv) a blend of an acrylic acid polymer with at least one of a sulfonic acid polymer and a phosphonic acid polymer, or a salt thereof. A deep mix soil stabilization method comprises drilling into soil while injecting a soil dispersant and subjecting the soil and the soil dispersant to mixing to form a soil and soil dispersant mixture, said soil dispersant comprising at least one of i) an acrylic acid polymer or copolymer, or a salt thereof, ii) an acrylic acid/sulfonic acid copolymer, or a salt thereof, iii) an acrylic acid/phosphonic acid copolymer or a salt thereof, iv) a blend of an acrylic acid polymer with at least one of a sulfonic acid polymer and a phosphonic acid polymer, or a salt thereof; and, mixing a cementitious binder with said soil and soil dispersant mixture to form a predominantly soil-containing stabilized soil.

    摘要: La présente invention concerne des produits de condensation et leur utilisation comme agents fluidifiants pour liants hydrauliques tels que les ciments, les plâtres et la chaux. Elle concerne plus particulièrement des produits susceptibles d'être obtenus par condensation en milieu aqueux, d'au moins :

    un composé (a) disposant d'au moins deux fonctions amines,
    un aldéhyde (b),
    un acide (c), comportant au moins un groupement SH, ou un sel d'un tel acide,
    un acide (d) comportant au moins une fonction amine ou un sel d'un tel acide,
    et éventuellement un ou plusieurs composés (e) susceptibles de libérer un ou plusieurs ions sulfonates.
