<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a porous lightweight construction material, comprising kneading ALC waste grains, which are used as inorganic pore-forming materials, with clay and molding and firing the kneaded product. <P>SOLUTION: In the mechanism of manufacturing a porous product by foaming as means for obtaining the porous product, a foaming aid and a melting aid are added to a clay base to induce chemical change of components, which leads to generation of a gas and formation and growth of pores in an internal structure of the clay due to melting, expansion, foaming, etc., of a foaming ingredient. In the method of manufacturing the porous lightweight construction material product of the present invention, grains of ALC (autoclaved lightweight concrete) waste are used as the inorganic pore material and kneaded with clay, and the resultant product is molded and subjected to biscuit firing or glost firing. This enables the manufacture of the porous lightweight construction material product without resorting to any chemical change such as melting of a glass component at firing and foaming by a gas. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
