Abstract:

Concrete is the mixture of cement sand and aggregate with a designed water-cement ratio. In RCC structural’s concrete is vibrated heavily to flow through reinforcement bars which are less spaced. To solve this problem self compacting concrete is used. In this research ordinary Portland cement is partially replaced with silica fume and fly ash with different percentages 5%, 10%, 15% and 20% of fly ash and 1%, 2.5%. 5%, 7.5% and 10% of silica fume for controlled mix design. In this research, the fresh and the hardened properties of concrete is determined it is shown that the fresh property of concrete is increased by increasing the percentage of silica fume and fly ash. It is observed that the mechanical properties of concrete are increased by the increase of silica fume and decreased the mechanical property by increasing the percentage of fly ash.
