摘要： A method for recycling waste concrete into molding sand is provided to increase air permeability and collapsibility by discharging carbon dioxide and steam by reacting calcium hydroxide and calcium carbonate by the heat of molten metal. A method for recycling waste concrete into molding sand comprises the steps of: removing foreign materials included in the waste concrete; crushing the waste concrete; sieving the crushed waste concrete in the size of 20~70 meshes; sending the crushed materials larger than 70 meshes, to a waste concrete crushing step; and drying the sieved waste concrete at 120~180°C. Calcium hydroxide and calcium carbonate of 1~5% are stuck on the molding sand. Calcium oxide is generated and then, steam and carbon dioxide are generated in pouring molten metal of 900~1200°C into a casting mold. Accordingly, air permeability is increased by discharging steam and carbon dioxide out of the mold.
