Innovative Approach to improve Concrete Properties

"Nanotechnology is one of the most active research areas which has wide applications in different fields. As the concrete is the most usable material in construction industry, a continuous need is required to improve its quality. According to research in recent years, nano-concrete is defined as a concrete made by Portland cement and cementitious particles with sizes smaller than 500 nm. Four nano-materials have been used in concrete, namely: Carbon Nano Tubes (CNT), Nano-SiO2, Nano-TiO2, and Carbon Nano Fibers (CNF).
Literature review revealed that well dispersed nano particles enhance the properties of fresh and hardened concrete.
