The use of nano materials over other SCMs is high reactivity, less quantity required, resulting in less cement replacement and cost efficiency. nano technology has taken over the world of ‘concrete’ in a significant way and have generally been found to improve Thus, with improved nanostructure, manufactures may be able to redevelop materials which would work wonders for varied applications and usages. Without doubt it would be befitting to say that using such materials would also help save our natural resources. In addition, the use and effect of nanosilica and silica fume are still not fully understood. Observations are made after studying the literature.
