Abstract: In the fast developing countries like our India, we are consuming a larger quantity of cement for the infrastructure development, In this connection we are over using the natural resource their by questioning our future climatic condition for our country as well it leads to the global warming. To reduce the conception of these resource we need to start practising the usage of pozzolanic content which is already available in south India’s Manchester Coimbatore, Tamilnadu. In this study GGBFS (Ground granulated blast furnace slag) which is available in plenty as a waste from mortar manufacturing companies in Coimbatore used as a Nano mineral admixtures which contains pozzolanic properties. It is similar to that of cementit is used as a Nano material obtained by grinding in a ball mill machine. In Nano technology area research have been done but particularly for GGBFS is not available. The GGBFS is available only were the steel manufacturing areas are more. In this paper we studied the mechanical properties of NanoGGBFS and compared the results with normal concrete (M30). The percentages of Nano mineral admixtures added to cement are 1%, 2%, 3%, 4% & 5% in this we got 4% Nano mix to the weight of cement is the optimum value after which the strength starts to decrease. To determine the size of particle and the chemical composition we have done the particle size analysis , SEM analysis as well the EDOX test.We conclude by saying that it contains silica and little amount of iron which is controllable and contain more amount of lime it will help in binding along the cement and gives good compressive strength. Through this the material will be used for construction purpose and we can avoid in dumping into the agricultural lands during rainy season the materials mixes with rain water and damaging the ground water with high hardness.
