The structural clay tiles are the kind of burned-clay construction materials that are used in constructing roofs, walls, and flooring for structural as well as non-structural purposes, particularly in fireproofing applications. These are also called structural terra cotta, building tile, clay block, and hollow tile; the material is an extruded clay mold having a substantial depth that allows it to lay in the same manner as the other clay or concrete masonry.
Clay tiles are also called roof tiles. These tiles are manufactured using the similar method as used for bricks. But, the tiles are lighter and thinner. For the manufacturing of clay tiles, the clay used should be highly plastic. After being moulded into the required shape, they are burnt at 1300° C. In this burning procedure, colouring admixtures can be used. The burning process is generally carried out in kilns.
