Usage of Carbon nanotubes and nano fibers in cement and concrete: A review

Abstract

Abstract-Carbon Nanotubes (CNTs) are basic carbon consisting of curved graphene layer which consists of a single layer of atoms in a combined hexagonal structure. After plenty of years several characterization of the carbon Nanotubes has become very popular in various applications in civil engineering. Carbon Nanotubes shows good results in terms of mechanical properties of cement mortar when added to it. Literature has showed that carbon Nanotubes can be used in the manufacture of the concrete and the cement pastes. This paper represents the summary of the various research works on the usage of the carbon nanotubes in cement paste, mortars and concrete.
