Abstract

Mangalore roof tiles are the oldest and the most popular patent tiles since ages because of nostalgic and evocative use in buildings. The tile industry in the west coast is almost 152 years old. It was introduced in this region by German Missionary in 1860 after they found that large deposit of clay in the banks of the rivers were available. But in recent times the roofing tile industries have been facing problems due to non availability of good clay. The clay available for the manufacture of tiles is deficient in plasticity and more sand content. Due to this, the tiles manufactured are heavier and less impermeable. In order to overcome these problems, fly ash which is available in large quantities in the country as a waste from thermal power plants is used as an admixture along with a small percentage of cement and lime to improve the index and strength properties of the poor clay available for the manufacture of tiles. An attempt is made to carry out an investigation to study the strength behavior of clay by blending with fly ash. In order to improve its plastic behavior and to make clay-fly ash mixture more plastic, an experimental investigation is also carried out by blending the clay-fly ash mixture with cement and lime (1%, 3% and 5%). With the addition of fly ash there is increase in the unconfined compressive strength.
