INTERNATIONAL STANDARDS TO INNOVATIVE CERAMIC SOLUTIONS

Porcelain stoneware is a ceramic with a compact, hard, coloured and non-porous body. It is largely used as building materials, for a quality architecture, offering high resistance to impact, stress, wear, scratching, frost, chemical attach and stains. It is produced in flat tiles, billions of tons per year. A very prominent technology, based on a pyroclastic deformation, permits to obtain bended porcelain tiles as innovative solutions for a modern architecture. This technology is grounded on a proper combination of heavy machining by cutting tools and secondary firing in a kiln. This new element, the bended tile, can be used in several innovative applications (as steps, shelves, benches, radiators…). But, new functions require a better and in-depth knowledge of these materials, especially referring to the mechanical proprieties. This paper investigates the limits of applicability of ISO standards for the quality classification of ceramics and experimental measures of their mechanical proprieties Keywords: Ceramic Industry, Grès Porcelain, Secondary
