Ground Granulated Blast Furnace Slag (GGBFS) and Metakaolin are cementitious materials used as admixtures to make top notch concrete and to lessen the permeability. Moreover, Ground Granulated Blast Furnace Slag is used to make durable strong structures in blend with standard Portland concrete. In spots where lacking or poor reestablishing strong structures like seashores, underground structures which experience extraordinary loss of compressive quality and vulnerability interconnected strength, use of Metakaolin and GGBFS in a perfect degree shows to be profitable to modify the properties of concrete. This endeavor deals with the properties of concrete, with contrasting rate substitution of GGBFS and Metakaolin as an inadequate exchange for security. The mix was obtained by designing (35%, 15%); (40%, 10%) and (45%, 5%) mass of cement by GGBFS and Metakaolin separately. Finally, required models were cast to consider rehearses, for instance, compressive quality, unbending nature, and robustness. Compressive quality and bonding tractable test were accomplished for testing the quality properties and sorptivity test was directed to check the toughness properties of bond. The test results showed that the two admixtures GGBFS and Metakaolin, when used at a perfect blend, will by and large increase the quality and durability of strong when differentiated and customary concrete. The objective of this assignment is to consider the assortments in quality and solidness characteristics of amazing strong mix by partial overriding of cement with different paces of GGBFS close by Metakaolin. The specific objectives of the undertaking are to consider the compressive quality and unbending nature of laboratory concrete with that of bond made by overriding bond with GGBFS and Metakaolin and to consider the quality properties of concrete made by replacing bond with GGBFS and Metakaolin.
