ABSTRACT:
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.
