摘要： PROBLEM TO BE SOLVED: To provide a cold hydraulic treating material which is free from pollution and has secured shelf life and to provide an effective utilization method for the treating material. SOLUTION: The treating material is prepared by adding active silica, a sulfate and an aid composition (phosphate composition, barium salt composition, or the like) into inactive calcia glass and forming the mixture into one pack. The modified or treated material and a formed article are obtained by a process for mixing a single material comprising the treating material or a one prepared by combining the treating material with an objective base material (sand particle body, hydrated soil, a contaminated base material, or the like) with a water based active agent and a working process comprising, if need, a process for forming and an aging process. The active silica is an alkali silanol base material expressed by formula (1) [ in formula (1), M is hydrogen, Na or K], and the sulfate is a sulfate-containing compound containing an oxyacid salt compound expressed by formula (2) [in formula (2), M is an alkali metal, Z is an alkaline earth metal and R is Al or 3-valent iron].

摘要： PROBLEM TO BE SOLVED: To provide a technology modifying concrete waste used for buildings and civil engineering field, which generally shows high alkalinity with water elution pH value 9 or higher and contains water-soluble toxic hexavalent chromium having adverse effect on ecosystem and living environment, into a pollution-free type and recyclable material with suppressed elution of the alkaline components showing high alkalinity and toxic hexavalent chromium. SOLUTION: In this modification method, a modification solution formed by dissolving a reforming composition containing silica component, alumina component, sodium oxide component and oxyacid component of sulfur as main components with a reducing component added thereto if necessary, into an aqueous solvent, is brought into contact with pollution type concrete debris having water elution pH value 9 or higher and containing water-soluble hexavalent chromium. The water elution pH value of the concrete debris is neutralized to pH 8.5 or lower, and water elution of coexisting hexavalent chromium is fixed and insolubilized to a range below the environmental regulations.
