COMPARISON BETWEEN KAOLIN AND QUARTZITIC CLAY PERFORMANCE IN THE EFFECT OF WOOD ASH ADDITION ON THE MECHANICAL AND OTHER PROPERTIES OF PORCELAINISED STONEWARE TILES
Porcelain represents the foundation of the ceramic discipline and one of the most complex ceramic materials. Composed primarily of clay, feldspar and quartz, porcelains are heat treated to form a mixture of glass and crystalline phases. This focuses on raw materials with the addition of wood ash processing and mechanical behaviors. The use of wood ash as in manufacturing ceramic tiles can increase the utilization, as well as reduce the cost of raw materials in the tile industry and provide a competitive edge to Nigerian tile Manufactures against foreign competitions. Ring was taken ensured completion of the pozzolainic reactions instituted by the wood ash and the production of dense compounds acting as filler within the pores of the porcelain mass. It was also found that the higher the wood ash content in the porcelainª¤? the lower their strength and density, the permeability 5-10 % cow dung un clays is the best ratio that gives the desired combination of opposing qualities and density, thus the ratio that gives the optimum mechanical and other properties. It was noticed from this research work, clay with kaolinitic content is better used than clay with quartzitic content in formulating porcelainised stoneware tile specimenª¤? consisting of the mixture of both quartizitic and kaolinitic clay has better performance than ordinary quartzitic clay sample.
