Nanotechnology is one of the most promising areas of science. The main use of nano particles in concrete is one of the new revolutionary steps in concrete technology. In this paper, an attempt has been made to understand the influence of Nano-Metakaolin as a partial replacement substance for cement in concrete. An experimental investigation has been carried out to determine the compressive strength and split tensile strength normal cement concrete and concrete containing Nano-Metakaolin partially replacing cement at various percentages. The ratio mixes were calculated from design code using IS 10262-2009. The fine aggregate was replaced by Nano-Metakaolin at various percentages 8%, 10%, 12%, 14%, for M 60 grade. A comparison between the cost of Normal Concrete and concrete with Nano-Metakaolin is going to made. It is found that partial replacement of cement with Nano-Metakaolin has a greater influence on the strength of concrete. The optimum percentage at which cement can be replaced with Nano-Metakaolin is going to be found.
Durability tests such Acid attack, Sulphate attack and alkaline attack was conducted. From the result it can be concluded that Nano-Metakaolin should give the improve performance and will get the optimum percentage of Nano-Metakaolin.
