Abstract: The use of Marble Powder and Silica Fume in the present days is to increase the strength of cement concrete. In this research Compression of the two materials one is Marble Powder and another is Silica Fume. Is this study there are two content are involved, first is that The silica fume are replace by 0%, 2.5%, 5%, 7.5%, 10%, 12.5%, 15%, 17.5%, 20% ,22.5% and 25% and Marble Powder are replace by 10% common for all mixes as a partial replacement of cement for 7, 14 & 28 days for M30, and M40 grade of concrete. Second is that the Marble Powder are replace by 0%, 2.5%, 5%, 7.5%, 10%, 12.5%, 15%, 17.5%, 20%, 22.5%and25% and Silica fume was replace by 10% common for all mixes as a partial replacement of cement for 7, 14 & 28 days for M30, and M40 grade of concrete. Casted 150 mm X 150 mm X 150 mm cubes for Compressive strength,100 mmX100 mm X500 mm beams for Flexural Strength, and Slump cone for workability of concrete and other properties like compacting factor and slump were also determined for three mixes of concrete. The use of cement and production of cement creates much more environmental issues& costlier. To avoid such circumstances, the content of cement is reduced in concrete and replaced by silica fume which reduces cost & addition silica fume also increases strength. Concrete is the most widely used and versatile building material which is generally used to resist compressive forces. By addition of some pozzolanic materials, the various properties of concrete viz, workability, Strength, Resistance to cracks and permeability can be improved. Many modern concrete mixes are modified with addition of admixtures, which improve the microstructure as well as decrease the calcium hydroxide concentration by consuming through pozzolonic reaction. The subsequent modification of the micro structure of cement composites improves the mechanical properties, durability and increases the service-life properties.
