NOTE: see the PDF version Varieties of floor tiles are amongst many of the specialties in ancient Sri Lankan architectural wonders. Even today floor tiles in Sri Lanka claim a high regard in world export market being one of the biggest equity grosser in commodities. Stone floors are admired for their splendid appearance as well as for higher durability. Natural stones such as slate, granite, gneisses and marble are commonly used for interior designs and flooring. Stone floor tiles being materials which are always in physical contact with moving objects are prone to wear, although at a comparatively slower rate. Therefore, the durability of tiles should also be of concern in addition to their aesthetic appearance. However, wear resistance of stone floor tiles has not been attracted adequate attention in material testing. Hence, it is essential to ascertain tribological properties, including resistant to wear, when selecting the most suitable flooring material. This research aims at investigating and documenting the wear resistance of commonly used Sri Lankan rocks in flooring.
