Abstract :
Self compacting concrete (SCC), which flows under its own weight and does not require any external viation for compaction has revolutionized concrete placement. It is highly workable concrete that can flow under its own weight through restricted sections without segregation and bleeding. Several admixtures have been developed to improve the strength and workability properties of concrete. Of all admixtures used in concrete, Metakaolin occupies a special position for quite a few reasons. The improvement of durability, resistance to chloride, sulphate, freezing and thawing, alkali silica reaction, frost attack, increase in compressive strength, reduces the permeability and bleeding. Quarry dust, a by–product from the crushing process during quarrying activities is one of such materials. Granite fines or rock dust is a by–product obtained during crushing of granite rocks and is also called quarry dust. In recent days there were also been many attempts to use Fly Ash, an industrial by product as partial replacement for cement to have higher workability, long term strength and to make the concrete more economically avaiable. The present experiment is carried out to investigate the fresh and hardened properties of ternary blended self compacting concrete with 10% of Metakaolin and 30% of fly ash by weight of cement as partial replacement of cement and addition of 0%, 20%, 40% and 60%of Quarry dust as fine replacement.
