초록

A liquid alkali metal silicate composition comprises water, an alkali metal, e.g., sodium silicate, glyoxal, optionally a Group I-III metal salt, e.g., calcium chloride, and hydrogen peroxide, and from 0.5 to 2.0 moles of a polyhydroxy compound per mole of glyoxal used. The specific polyols are mannitol, glycerol and sucrose. This composition is easily pumpable and injectable at a temperature of 100° F. or higher.

청구항

1. 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 into said composition, for each mole of glyoxal used, from 0.5 to 2.0 moles of a polyhydroxy compound selected from the group consisting of mannitol, glycerol and sucrose, whereby the gel time of the resulting composition is significantly inhibited by comparison to a liquid alkali metal silicate-glyoxal composition and it is easily pumpable at an application temperature...
