The effect of using multi-walled carbon nanotubes on the mechanical properties of concrete: a review

Nanotechnology has grasped the attention of scientists in several fields during the past decade because of its huge role in developing unique characteristics and behaviors for materials, as it deals with understanding, controlling, and modification of matter at the atomic level in the range of 0.1-100 nm (10-9 mm). Nanotechnology could be a paradigm shift in the civil engineering field as the studies showed that inducing different types of nanoparticles in concrete contributed dramatically to improving the mechanical characteristics and durability of concrete as well as creating innovative properties such as self-sensing, self-cleaning, fire-resisting, etc. This paper will show the recent results that were concluded by researchers about the effect of adding nanoparticles in construction materials and especially the effect of multi-walled carbon nanotubes as an enhancing material.
