On 4/3/2018 scientific visit had been organized by: Dr. Sura Salim Ahmed, Dr. Hana Aareer Smeij, Lec. Mervat Mehdi Hanoos, and Assist.Lec. Mina Faisal Khudair, Faculty of Materials Engineering / University of Technology. The students of the third stage in the Ceramics and Building Materials branch/ Department of Materials Engineering visited the National Center for Structural Laboratories for the laboratory tests; it includes a number of laboratories for ceramics and building materials, including the concrete laboratory for the physical and chemical tests of the thermal bricks and floors. The students knew several types of tests carried out inside the laboratory, the most important of which are: the strength of the fracture, the hardness test, the absorption test, chemical resistance test against specific acids and corrosive solutions that may ceramic products exposed to, as well as the test of thermal conductivity for floors and bricks.
