<p><P>PROBLEM TO BE SOLVED: To provide a shirasu and plastic-blended concrete product which is lightweight and has high strength. <P>SOLUTION: In a method for producing a molding product, a granular material obtained by kneading volcanic ash (shirasu) being a base material and various plastics is used as aggregate, and cement is used as a binder, then water is added to these raw materials, the resulting mixture is kneaded with a concrete mixer, and the kneaded mixture is cast into a molding flask. Because the shirasu and plastic-blended concrete product is lightweight, the transporting cost of the shirasu and plastic-blended concrete product is reduced and the shirasu and plastic-blended concrete product is simple to handle in comparison with a secondary product obtained by kneading sand, crushed stone, cement and water, like a common concrete product. The shirasu and plastic-blended concrete product can be used for constructing, especially, a garden facility or a roof-top greening facility. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
