Abstract
The present invention relates to liquid mixtures of alkali metal silicates, water, and trialkoxysilanes of the general formula R--Si(OR').sub.3, which harden to form silica-containing gels within a predetermined length of time. The mixtures can contain additional means for influencing the gelling and the gel strength. The most important field of application of the gels in accordance with the invention is the stabilization of soils in architecture and civil engineering.
