PURPOSE:To provide a curable composition consisting of a suspension of lime and a solution obtained by neutralizing alkali in water glass, which has sufficient fluidity for a long time after pouring and flows within a predetermined area only. CONSTITUTION:The composition is prepared by blending a suspension which contains lime as effective ingredient, with a solution obtaned by interaction of an aqueous water solution of water glass with CO2 gas, for neutralization of alkali components in the water glass to a pH of 6.0-9.0 in such a blend ratio that concentration of SiO2 derived from the water glass may be 0.03-0.3mol/l. EFFECT:The curable composition does not cause bleeding after solidification nor makes underground water alkaline. |
