HYDRAULIC COMPOSITION
PROBLEM TO BE SOLVED: To obtain a hydraulic composition capable of reducing the elution of Cr6+ even if waste containing the Cr6+ or the like is used. SOLUTION: The hydraulic composition contains cement and a material for reducing elution of heavy metals, and the material for reducing elution of the...

| description | PROBLEM TO BE SOLVED: To obtain a hydraulic composition capable of reducing the elution of Cr6+ even if waste containing the Cr6+ or the like is used. SOLUTION: The hydraulic composition contains cement and a material for reducing elution of heavy metals, and the material for reducing elution of the heavy metals is manufactured under a reducing atmosphere at >=1,000 deg.C and consists essentially of three components of CaO, Al2O3 and SiO2 as chemical components, and contains CaO of >=20 wt.%, Al2O3 of |
