Zusammenfassung:	PURPOSE:To obtain a solidifying material outstanding in curability and strength, for use in high-organic matter sludge of high water content and peat, by grinding or classifying a mixture of specified proportion of blast furnace granulated slag, Portland cement clinker and gypsum into ultrafine powder. CONSTITUTION:The objective solidifying agent for incorporation in pozzolana soil, sandy soil or soil predominant in sand content followed by agitation to develop high strength can be obtained by grinding or classifying a total of 1,000pts.wt. of a mixture prepared by blending (A) 100-900pts.wt. of blast furnace granulated slag, (B) 100-700pts.wt. of Portland cement clinker and (C) 50-200pts.wt. of gypsum into ultrafine powder with a fineness (Blaine value) of 6,000-14,000cm /g beyond common sense for conventional cement-based materials.
