Abstract
The paper aims to study the properties of various local and imported terrazzo tiles manufactured by ten different factories. Five of the terrazzo tile samples are local while the others are imported from Turkey and Iran. Thirty samples have been tested for each factory with total number of 300 tiles. Samples of tiles have been randomly selected from local market and then tested according to the testing methods of terrazzo tiles and ordinary tiles (31, 1989) and compared with Iraqi specification (1042, 1984). Tests result showed that all local samples conform to the specification while imported samples do not conform to Iraqi specification. The Turkish samples were out of tolerances in thickness (-15, -13 mm) for both samples. The Iranian samples were out of limits in total absorption test (10.4, 11.6 %) for both sample. The higher modulus of rupture was 7.22 MPa in a Turkish sample. The best abrasion resistance was 1.87 mm average thickness reduction in an Iranian sample. The best result of SO3 content was 0.274% in local sample Kamalyah factory. Over all, according to the adopted specification all local samples can be classified as conformable to specification limits.
