Mechanical properties related to use of glass waste as a raw material in porcelain stoneware tile mixtures

Porcelain represents one of the most complex ceramics, formulated from a mix of clay, feldspar and quartz are sintered to conform a glass-ceramic composite. Porcelain stoneware tile has excellent technical characteristics. Nowadays, research of new materials, for example non-hazardous wastes, that are able to replace the traditional fluxing agent with out changing the process or quality of the final products has been realized. The aim of this work is to study the possibility of the use of glass powder waste, in ceramic mixtures, for manufacturing of porcelain stoneware tiles. It was prepared by mixtures containing different amount of fireclay, glass waste, feldspar and quartz. The samples were fired reaching different maximum temperatures in the range 900-12000 C, with a soaking time of 1 hour. The fired samples were characterized and the use of small amounts of glass powder in addition with feldspar and quartz showed good results of mechanical technological properties. The 10F5Q5G was the only product that can be classified as a porcelain stoneware tile due to its properties

Measurement of Natural Radioactivity in Porcelain Stoneware Tiles

This paper presents the results of the measurement of natural radio activity present in the Porcelain stoneware tiles samples collected from the ceramic firms of Government Ceramic institute, Virudhachalam.  Natural radioactivity in the porcelain stoneware tiles samples in mainly due to 226Ra, 232Th and 40K and their daughter products.  In this study, these measurements have been estimated in Gamma-ray spectrometry and their levels for six samples are compared and also the Radium equivalent concentration (Raeq) is calculated. The gamma index is calculated and compared well with the reported values
