Zusammenfassung:PURPOSE:To obtain a filled layer having excellent strength by utilizing effectively cinder discharged in great amounts by a method in which the cylinder is mixed with steel-making slug and gypsum to a slurry, and the slurry is packed and solidified in low ground or mining sites. CONSTITUTION:Coal cinder, e.g., clinker, flyash, etc., is finely ground and also steel-making slug is ground by a grinder to grain sizes (Blaine value) of 3,000- 4,000. Then, 100pts.wt. cylinder powder, 10-50pts.wt. steel-making slug, 10- 50pts.wt. gypsum, and 30-60pts.wt. (based on total weight of solids) water are mixed together to form a slurry. The slurry is packed in a low ground or mining site and slowly solidified by hydration reaction. Thus, after the lapse of a curing period of 28 days, a solidified packing having excellent strength (26.0kg/ cm ) can be formed.
