Abstract The present article is the review for analyzing the potential use of Nano particles like carbon nanotubes, Silicon dioxide, oxides of titanium, Iron, copper, aluminum, chromium and calcium carbonates etc. nanoparticles for construction and highway engineering. The Nano technology considering Nano science and Nano engineering for civil engineering has been explored. The factors like quality, strength, durability, workability etc. are considered for comparison of different effects of Nano particles and there applicability for the construction and highway projects. The field for Nano particle incubation is required to more study and analysis. The review results observed that the enhancement of Nano technology now should be concentrated for construction and civil application.
