Abstract: A broad range of challenges faced by the construction industry today deals with both the short term & long term effects of new material use in cement. This paper aims to explore the fact that that small addition of nano particles viz. Nanosilica (nS), Carbon Nanotubes (CNT) & Nano Titanium Oxide (TiO2) in ordinary Portland cement have enhanced both the short term & medium term strength of cement mortar when added in optimized quantities with respect to the weight of cement & water added as per the normal standard consistency formula of the Indian standards. However, in the long term (90 days & above) it is seen that with increase in the quantities of all the nanoparticles from the optimized one to a bit little further, further increases the same. With the increase of the optimized nS to 1% showed a strength gain of more than 12% and 8% at 180 days and 365 days and with the increase from optimized CNTs to 0.1% saw a strength gain of more than 23% at 180 days and 69.21% at 365 days. However,increased addition of optimizedTiO2 w.r.to its optimized quantity did not serve any better results.
