Abstract
A hydrous composition for stabilizing finely divided soils comprises a gum swellable when hydrated, such as sodium alginate; water; and an alcohol, such as methanol, in an amount sufficient to prevent the composition from setting prior to use. The composition is added to finely divided soils in an amount of about 5-25 gallons per foot mile per 6 inch lift. A hardener having a source of calcium, such as CaCl.sub.2, is applied to the soil to harden the composition.
Claims21
A method of stabilizing soil comprising adding a stabilizing composition to a soil at a concentration of about 5-25 gallons of the composition per 1000 gallons of water per 6 inch lift, the composition comprising a hydratable gum in an amount effective in providing positive bonding between granular particles, water, and a monohydric alcohol having 1-4 carbon atoms in an amount of at least 25% by volume based upon the volume of alcohol and water in the composition.
