Abstract
PURPOSE: To provide the title hardener whose gelling time can easily be controlled and which can be used in both fields of flash-setting grout and slow- setting grout, containing glyoxylic acid or a salt thereof as a main agent.
CONSTITUTION: 1W10wt% glyoxylic acid or salt thereof as a hardener, 10W 50wt% (on a solid basis) water glass, and water are mixed together. To this mixture is added an alkali such as NaOH or KOH to neutralize partly or wholly the carboxyl group of glyoxylic acid and to controll the curing time. Then the mixture is injected into soil.
