<P>PROBLEM TO BE SOLVED: To provide a method for producing a water cleaning material at low cost. <P>SOLUTION: The hydration of a cement content is performed by mixing at least either of a concrete waste containing cement and a cement with water, dispersing at least one of cement and the concrete waste into water, and making the hydration reaction of the cement content progress. The cement content after hydration is separated into a cement hydrate and a hydration water by solid-liquid separation. The obtained cement hydrate being a solid content is heat-treated to obtain a water cleaning material. Since such a method for production of the water cleaning material does not need any particular facility or process, the elevation of production cost can be prevented. Further, since at least one of cement and the concrete waste, and water only are used as raw materials, the increase of raw material cost can also be prevented and thus, the water cleaning material can be produced at low cost. <P>COPYRIGHT: (C)2013,JPO&INPIT |
