Large volume of Groundnut shell and Ground Granulated Blast Furnace Slag (GGBS) are disposed directly from the industries on the land without doing any further treatment. These discharged waste materials are making nuisance to the environment, when it was discarded over the earth surface and thus making the environmental issues and illness to the peoples. Therefore, it is planned to investigate the possibilities to use the Groundnut shell and Ground Granulated Blast Furnace Slag GGBS in the form of ash for the production of concrete in the construction industries for the replacement of cement. In this works, it is planned to perform the SEM and EDX analysis to predict the elemental components and size of Groundnut Shell Ash (GSA) and GGBS. By analyzing the results obtained by conducting the SEM and EDX analysis, it was examined that the size of the GSA and GGBS are less than 75m and 45µm respectively. The GSA and GGBS contains large amount of oxides of calcium, magnesium, potassium, silica and aluminium. The components and their proportions of the minerals of the GSA and GGBS are very match with the cement. Hence, it is suggested that the GSA and GGBS could be replaced for the partial replacement of cement for making concrete. Also, the size of the GSA and GGBS are less than the size of the cement particles and hence it will help to enhance the strength and durability properties of concrete matrix.
