Zusammenfassung:	PURPOSE:To provide a method for reclaiming concrete waste capable of utilizing in a large amount as a material for civil works and building structures. CONSTITUTION:A concrete waste is directly melted at a high temperature or blended with a Ca-based raw material, etc., and then the blend is melted at a high temperature. Further, the substance melted at a high temperature is scattered from a nozzle together with a high pressure gas and cooled and solidified in a scattered state. Thereby, the concrete waste is converted to a globular hydraulic substance.
