Nanotechnology is the use and study of matter or structure between 1 nanometer ( nm ) and 100 nanometers in size. It is the study to make use of matter at the molecular scale. As particle become nano-sized, the fraction of particle on the surface multiply virtual to those inside leads to “nano-effects” and alter the properties of the material to a great extent to produce material with novel and smart properties. Concrete, second highest consumed commodity on earth, with assimilate nanotechnology into material like concrete that will greatly improve its enviable chattels, such as strength, sturdiness, ductility, and cleanliness etc. Currently, the most dynamic research an area in terms of nanotechnology is it’s dealing with cement and concrete is: understanding of the hydration of cement particles and the use of nano-size ingredient. Also, Cement industry is one of the noteworthy sources of carbon dioxide emissions, which accounts for 5-6% of global man-made carbon dioxide emission annually. Recuperating the material resistances and the escalating of their durability will reduce environmental pollution by reducing the carbon footprint of the building. A considerable improvement in the mechanical properties and durability of cementitious materials can be observed with assimilation of nano materials such as nano- Al₂O₃, ZnO₂, TiO₂, SiO₂, Carbon nanotubes, etc. Hence if the performance of the basic civil engineering raw materials is enhanced anyhow, the productivity will get increased as to work with those modified materials and the performance of the final civil engineering product will also be improved in the benefit of mankind.
