Concrete is a blending of cement, sand, coarse aggregate and water. Concrete is broadly used and is one of the mostly utilized building materials available in the world. It is the one of the greatest used element in the world next to water, this study aims at utilization of industrial by product such as Metakaolin, Ultrafine fly ash,Nano silicaetc, for value added application. In addition the waste used can improve the properties of construction materials. TheMetakaolin, Ultrafine fly ash,Nano silica has been used in this project. The above mentioned materials were tested as concrete ingredients. Cement was partially replaced by Metakaolin, Ultrafine fly ash,Nano silica with different mix proportions along varying percentage ofMetakaolin, Ultrafine fly ash,Nano silica for concrete with suitable water cement ratio.The Compressive strength, Split tensile strength and Flexural strength were conducted for the above replacements. The results showedMetakaolin, Ultrafine fly ash,Nano silica improves the mechanical properties and strength of concrete. The advantages of this project are that the partial replacement of cement with Metakaolin, Ultrafine fly ash,Nano silica which are economically cheap and eco-friendly as well as a superior concrete can be produced.
