[Problem] To provide a non-polluting, normal temperature hydraulic treatment material with shelf life ensured and a method for utilizing the treatment material. SOLUTION: Active silica and sulfate, and auxiliary compositions (phosphate radical composition, barium salt composition, etc.) are added to inert calcium glass, and one-packed to obtain a treatment material. Work consisting of a single material made of treated material, or a process that combines the target material (sand granule, hydrous soil, contaminated material, etc.) with the treated material and mixed with an aqueous activator, and if necessary, a molding process and a curing process Depending on the process, it is modified or processed and molded. The active silica is represented by the formula 1 [Wherein M is hydrogen, Na, K], an alkali silanol material represented by the following formula 2 [Wherein M is an alkali metal, Z is an alkaline earth metal, R is Al or trivalent iron] and a sulfate group-containing compound including an oxyacid salt compound.
