PURPOSE:To obtain a soil property hardener, capable of rapidly hardening hydrous soil and preventing the ground from weakening and useful for civil engineering works, etc., by blending a highly water absorbing resin with a compound such as a sulfite. CONSTITUTION:The objective soil property hardener is obtained by blending (A) a highly water absorbing resin such as a cross-linked acrylic salt polymer with (B) one or more compounds selected from sulfites such as sodium sulfite, L-ascorbic acid and ferrous salts such as FeSO4. Furthermore, the blending weight ratio of the components (A) to (B) is preferably (2000/1) to (1/10). |
