Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method and apparatus for simply and inexpensively improving properties of construction sludge from various construction sites to effectively utilize the sludge without the need for landfill in a safety controlling type final disposal site. SOLUTION: The method and apparatus are for solidifying the construction sludge to improve its properties, wherein the cone index of the construction sludge is made equal to 200 kN/m2or above by loading it with molten slug recovered and rendered harmless in a waste melting furnace, or powdered or fine powdered molten slug with an alkaline material such as slaked lime or a sulfate material such as gypsum.
