Abstract: The aim of this study is to evaluate the performance of Fly Ash and Silica Fume (replacement) a mineral admixture in concrete when it is mixed in cement concrete for workability, durability and strength of concrete using OPC (53- grade). Concrete over the past few years suggest that cement replacement materials along with mineral & chemical admixtures can improve the strength, workability and durability characteristics of concrete. The research has focused on developing selfcompacting concrete in cooperating relatively large amounts of mineral by products such as Silica Fume and Fly Ash as supplementary cementing materials. This study investigates the performance of concrete mixture in terms of Compressive strength and split tensile strength for 7, 14 and 28 days respectively of M-30 grade concrete. This project deals with the self- compacting concrete where the replacement levels of OPC by Fly Ash were 15%, 20% and 25%, where replacement levels of OPC by Silica Fume were 6%, 9% and 12% by weight. Here in this project 1.2% of super-plasticizer was used in all the test specimens for better workability at lower water binder ratio and to identify the sharp effects of Silica Fume and Fly Ash on the properties of concrete. These Concrete specimens were deep cured in water under normal atmospheric temperature.
