ORGANIC SOLIDIFICATION MATERIAL FOR POOR GROUND

PROBLEM TO BE SOLVED: To obtain the subject material by including a slag composite with a specific composition obtained through incinerating and fusing various kinds of waste products, etc., to make into slag and to utilize the slag composite effectively. SOLUTION: This slag composite is effectively utilized by blending it with Portland cement, blast furnace slag and gypsum, etc., as a component of an organic solidification material for poor ground. The above slag composite comprises (A) 0-37wt.% CaO, (B) 23-90wt.% SiO2 , (C) 0-40wt.% Al2 O3 , (D) 0.1-50wt.% at least one kind selected from a group of iron oxides, alkalis, phosphorus, titanium oxides, manganese oxides and magnesium oxides and/or (E) 0.1-10wt.% halogen.
