  • Method for producing enhanced soil stabilization reactions between lime and clay soils due to the effect of silica addition
    Patent number: 5336022
    Abstract: A method is shown for stabilizing clay bearing soils in which a silica compound is incorporated into the soils in addition to the application of lime. The silica compound can be either an amorphous, silica fume, a crystalline silica, a silica gel, sodium silicate, potassium silicate, finely ground glass or combinations thereof. The silica compound promotes the formation of calcium silicate hydrates over the formation of calcium aluminate hydrates in the resulting pozzolanic reaction occurring in the clay bearing soils. The silica compound and lime can be incorporated into the soils in a single step.

  • Method for preventing the adverse effects of swell in sulfate bearing, expansive clay soils
    Patent number: 5228808
    Abstract: A method is shown for stabilizing sulfate bearing soils in which a silica compound is incorporated into the soils with the soils being further stabilized by the application of lime. The silica compound can be either an amorphous, flume silica, a crystalline silica, a silica gel, sodium silicate, potassium silicate or combination thereof. The silica compound and lime can be incorporated into the soils in a single step.
