PURPOSE:To obtain a self-hardening stable fluid having superior characteristics comparable to those of a product using fresh water without increasing the amt. of bentonite by kneading a cement-based hardening agent, bentonite and sepiolite with a prescribed amt. of seawater. CONSTITUTION:When a hardening agent such as a cement-based hardening agent, bentonite and an additive are kneaded with seawater to produce a self- hardening stable fluid, 1-3wt.% sepiolite is used as the additive. A self- hardening stable fluid capable of forming a hardened body having strength and water permeability comparable to those of a hardened body formed by a product using fresh water is obtd. without increasing the amt. of bentonite used in the product kneaded with fresh water. |
