Nanocarbon tubes and Nanomaterials will be the gamechanger in the civil engineering industry in the coming days due to environmentally friendly and sustainable innovative design options to reduce the carbon emissions of producing cement by burning coal. The application in not limited to the field of Civil Engineering but in many more like Automobiles, Transmissions, Solar Energy, Wind Energy, Fiber lightweight bodies of war tanks, Ship Buildings, Medical fields, Mechanical and Electrical industries, and many more. Nanomaterials are having added advantages due to lightweight in reducing the foundation loads by reducing the supervenient of the bridge super structures, cable diameter in cable stayed bridges, ground improvement techniques, prevention of leakages, preventions of cracks, preventions of corrosion in reinforced concrete elements and useful materials for repairs and renovations. This paper represents the research and studies carried out all over the world for the sustainable and optimal use of Nano materials namely nanocarbon tubes, nanocarbon powder, nanocarbon materials, nanofibers, nano-silica, titanium dioxide which provides the improvement of the strength of concrete and cement paste and reducing the cracks development with prevention of corrosion of rebars. This paper will help future researchers to get the most recent work done in nanotechnology in various parts of the globe.
