    摘要： A method is disclosed for improving the strength and impermeability of soils or engineering structures, which comprises the steps of:(a) applying to the site of the soil or of the engineering structure, an alkaline water glass solution comprising water glass in an amount of 15 to 40% by weight, calculated as dry substance;(b) allowing a time period to pass sufficient to permit the alkali present in the water glass solution to move by diffusion;(c) applying to the same site as in step (a), a silicic acid sol comprising SiO.sub.2 in an amount of 5 to 50% by weight calculated as dry substance, and an organic dispersion medium in which 10 to 100% by volume of the dispersion medium consists of a water-miscible organic solvent capable of reacting with the alkali content of the water glass solution applied during step (a), thereby gellifying the water glass so that the reaction product of the water-miscible organic solvent and the alkali content of the water glass is trapped within the gelled water glass; and(d) allowing a time period to pass sufficient to permit the respective organic dispersion medium present in the silicic acid sol to move by diffusion, so that gellification of the water glass takes place evenly when mixing of the water glass solution applied during step (a) and the silicic acid sol applied during step (c) to the soils or to the engineering structures takes place to effect a plasticizing effect on the resulting water glass gel.

    摘要： A process for sealing geological formations and mine stoppings by applying to these substrates an aqueous, non-cementitious caulk composition comprising an alkali metal silicate; filler material including at least one silica product or silicate other than an alkali metal silicate; a water-soluble or water-dispersible acrylic polymer modifier; and water, and allowing the caulk composition to dry to form an air flow resistant seal on the substrates. A highly satisfactory polymeric modifier is used in the form of a polymer emulsion, such as an emulsion of a self-plasticizing acrylic polymer having a low Tg.
