description	With the growing progress in the use of concrete, novel technologies have been introduced into the production of this building material. Self-consolidating concrete (SCC) is one of the concrete types, which has been extensively applied in building industry nowadays. SCC could be empowered in terms of durability and mechanical properties and, as a result, the service-life of SCC and efficiency of concrete structures could be increased using complementary materials such as Pozzolans and nano-materials. Considering their structures, nano-materials such as nano-silica, nano-calcium carbonate and other similar materials could be helpful in making SCC. This paper aims to investigate the effect of nano-calcium carbonate and nano-silica on the durability and mechanical characteristics of SCC.
