Zusammenfassung:	PURPOSE: To produce an extrusion molded cement product excellent in weatherability and having high strength by continuously performing extrusion molding even when operation is repeatedly interrupted. CONSTITUTION: In the production of an extrusion molded cement product, the waste material of an extrusion molded cement product is ground and the obtained ground waste material is subjected to moistureproof treatment to be used as the fine aggregate of the extrusion molded cement product. A treatment agent used in moistureproof treatment is either one of a water impermeable resin or a water repelling substance and adapted so as to be sprayed on or mixed with the ground waste material. As the moistureproof treatment agent, the water impermeable resin such as clear lacquer (transparent lacquer) or the water repelling substance such as a silane moistureproof agent is used.
