Zusammenfassung:	PURPOSE:To break a durable structure safely and easily by drilling one or more of holes to the durable structure such as concrete, a rock, etc., inserting a composition for breaking having a specific composition and breaking the durable structure by the reaction of the composition for breaking and water. CONSTITUTION:The ground product of clinder being baked at a temperature of 1,200 deg.C or higher and containing a 1.0-40.0wt.% calcium aluminoferrite solid solution and free lime and free magnesial at 60.0-99.0wt.% in total weight is manufactured as a breaking material composition. Holes are formed to a durable structure to be broken by a drill, etc., and the aqueous slurry of the composition for breaking and water is introduced directly into the holes. Concrete, rocks, etc., are broken by utilizing expansion pressure generated by the hydration reaction of clinder. Accordingly, the durable structure can safely be destructed easily without generating environmental pollution.
