Abstract

In this paper, I have discussed about the use on Nano Technology in civil engineering. Under Nano Technology, Graphene and its oxides are being used as a game changer in the field of civil Engineering . Graphene and its derivatives when being used in the cement, improvs the mechanical as well various other property of fresh concrete as well as harden concrete. It has been found by the researchers that cement mixed with graphene and its derivatives such as graphene oxide, graphenenanoplatelets, and reduced graphene oxide show a rapid increase in its flexural, compressive and tensile strength. This special type of cement also shows its excellence in hydration rate, setting time, heat of hydration, workability, strain and damage sensing, Electromagnetic Interference (EMI) shielding, thermal and chloride diffusivity and crack repairmen. In this review how this modified cement brings changes in various property of concrete being discussed .This modification brought a desirable change in compressive strenght, flexural strength on harden concrete as well as the increment in the workability of fresh concrete.
