Abstract: The infrastructural development is an important aspect for the overall development of country. In all construction works concrete is an important and costly issue, this governs the total cost of project. To reduce cement consumption for environmental and economical concern, use of supplementary materials is required. In this work fly ash and metakaolin were used to decrease the cement contents and increase the strength as well as durability of cement. The main objective of this research work is to know the cement hydration mechanism, its strength with different ratio of fly ash and metakaolin. All mixes were made with water-to-binder ratio of 0.40. The results are evidences by chemical analysis, XRD, SEM, DSC, etc

Keywords: OPC (Ordinary Portland cement); Mk (Metakaolin); FA (Fly ash), Blended cement; C-S-H(Calcium silicate hydrates) ; SEM, XRD; DSC.
