Abstract: Plain concrete possesses a very low tensile strength, limited ductility, and little resistance to cracking. Internal micro cracks are inherently present in the in the concrete mainly due to drying shrinkage and its poor tensile strength is due to propagations of these micro-cracks eventually leading to brittle nature of concrete. Addition of nano fibres will result into arresting of micro-cracks and which will lead to improvement of static and dynamic properties of concrete. Cellulose nano-materials, cellulose nanocrystals (CNC) or cellulose nanofibrils (CNF), offer new possibilities for endowing cementations composites with improved mechanical performance. Their small size can allow a smaller inter-fibre spacing and more interactions between the cellulose and the cement system, and as a result, the CNC and CNF have a greater potential to combat micro-cracking and increase the strength of the system. This paper focuses on benefits which can be obtained by adopting Nanocellulose as a reinforcing material in concrete and review of research work carried out by various researchers to study effects of nano cellulose on concrete and benefits.
