<p>PROBLEM TO BE SOLVED: To obtain a lightweight non-fired tile having a good appearance and a high strength by press-molding a composition comprising field hollow ceramic particles having a water pressure-resistant strength and a melting point at specified values or larger, respectively, pulverized pottery particles, a cement and water into a tile-like product, and placing a thin plate-like core in the molded product. SOLUTION: This lightweight non-fired tile is obtained by pressing and molding a composition comprising a cement as a binder, fine hollow ceramic particles having a water pressure-resistant strength of >=600 kgf/cm2 and a melting point of >=1,500 deg.C, and pottery waste pulverized particles. Therein, a thin plate-like core is placed in the molded product. The obtained tile has a high strength and shows a rift-like surface pattern comprising the pottery waste pulverized particles. The fine hollow ceramic particles reflect light to generate excellent luster and excellent brightness on the surface of the tile. The core placed in the molded product includes various thin plates comprising metals, inorganic materials, plastics, etc., and preferably has a thickness of 0.5-15.0 mm.</p> |
