Nanomaterials in Construction Industry Image retrieved from: http://irannano.org/filereader.php?p1=main_f60512bd610678bba2d5d4838b7f4c19.JPG&p2=pr_brand&p3=21&p4=2 In modern construction field, most common used materials are concrete, glass, steel and timbers.  By the help of the improvement in nanotechnology, materials at nano scale offer enhanced properties for construction purposes.  Because, nano-materials can suddenly exhibit different properties compared to macro-scale. For example, Carbon Nanotube, one of the important nanomaterials, indicates 150 times higher strength value and approximately six times lighter than steel.   Studies in nano composites for improvement in cement performance are very important for construction industry. The materials such as Nano-Titania (TiO 2 ), Carbon Nanotube, Nano Silica (SiO 2 ) and Nano-Alumina (Al 2 O 3 ) can be combined with cement. These materials are densifying

·          * French chemist Paul Emilie Lecoq de Boisbaudran found the element of Dysprosium in 1886. He obtained Dysprosium Rare Earth Element through separating it from Holmium Oxide . ·          * Dysprosium Rare Earth Element is also a rare earth metal which is included in Lanthanide element family. Dysprosium   Rare Earth Element's atomic weight is 162.50. ·          * Dysprosium Rare Earth Element is bright, soft and silvery-white element is considered to be mildly toxic and acts        stable in room temperature. Dysprosium Rare Earth Element’s reaction with air happens very slowly. ·          * Dysprosium Rare Earth Element can be found in different minerals. ·          * Since this Dysprosium Rare Earth Element is useful for neutron absorbing, it is used in dysprosium-oxide-nickel cement and it is used in Nuclear Energy Industry. Like other, Dysprosium is also useful for magnet production.    * Dysprosium Rare Earth Element is also used in data storage application
