Production of Light Weight Ceramics Teils from Local Materials

This study covers the feasibility of production lightweight ceramics teils (light weight clay bricks) by adding local various types of combustible materials to the clay. It was found those substantial quantities of bagasse, sawdust, rice husks and straw are suitable for the production of lightweight bricks and distributed combustible materials finely was mixed with clay and molded into bricks. During firing in the kiln the combustible materials burnt out and leave air spaces, which contribute, to the high thermal insulation value of the bricks. It was possible to produce bricks with densities between 800 and 900 Kg m³ and thermal conductivity between 0.19 and 0.22 Kcal mh¹°C. The thermal conductivities were comparable or better than those of existing insulation materials on the market
