Soil-cement compositions, used for forming subterranean cementitious masses, are basically comprised of hydraulic cement, water present in the compositions in amounts sufficient to form slurries of the solids therein, a dispersant comprised of a mixture of sodium dihydrogen phosphate buffer, ferrous lignosulfonate, ferrous sulfate and tannic acid, and soil present in an amount whereby the volume ratio of cement, water and dispersant to soil in the compositions is from about 0.3:1 to about 2.1:1. |
