Abstract
An easily pumpable, liquid alkali metal silicate composition of controlled gelling characteristics comprises water, an alkali metal silicate, glyoxal optionally a Group I-III metal salt, e.g., calcium chloride and from 0.025 to 0.18 mole of hydrogen peroxide per liter of composition. This composition finds particular utility for stabilizing soil, the treated soil exhibiting enhanced load-bearing capacity.
Claims15
In a liquid alkali metal silicate composition curable to a solid upon standing and comprising water, an alkali metal silicate and glyoxal, the improvement which comprises incorporating from 0.02 to 0.7 mole of hydrogen peroxide per mole of glyoxal, whereby the resulting composition exhibits, upon curing, improved compressive strength.
In a method of stabilizing soil which comprises contacting said soil with a sole liquid composition comprising 10 to 70 percent, by volume, of an aqueous alkali metal silicate having an alkali metal oxide:silicon dioxide ratio of 1.0:3.0-4.0;
- about 0.25 to 1.05 moles of glyoxal per liter of composition;
- and water, the improvement which comprises adding to said composition about 0.025 to 0.18 mole of hydrogen peroxide per liter of composition, whereby emhanced load-bearing capacity is exhibited by soil treated with the composition.
