摘要：Self – compacting concrete (SCC) is a high – performance concrete that can flow under its own weightto completely fill the form work and self-consolidate without any mechanical vibration. Such concrete an accelerate theplacement, reduce the labor requirements needed for consolidation, finishing and eliminate environmental pollution.Oyster shell were collected from river and sea & it produced to powder from In this study, pozzolonic replaced withvarious percentages by oyster shell powder and the fresh and hardened properties of cement concrete were studied. Inthis study, cement content in the SCC mix is replaced with various percentage of 0%,.2.5%,5%,7.5%,10% and 20% ofoyster (River and Sea) shell powder is used and the fresh and hardened properties of cement concrete were studied. It isobserved that can be effectively used as a mineral additive in SCC. The Mix Design for concrete M25 grade is beingdone as per the Indian Standard Code IS: 10262-2009.Specimens (cube &cylinders) were cast to study the strengthproperties such as compressive strength (3, 7 , 14 and 28 days), split tensile strength (28 days), Flexural Strength (28days) and durability aspects such as water absorption (28 days). Water Binder ratio was maintained at 0.40. Testresults was indicate that concrete containing oyster shell power to an extent of 5% shows better strength characteristicswhen compared to the concrete with 0% of oyster shell power, whereas concrete with oyster shell power of 5%replacement shows optimum results better durability characteristics than the other percentage replacements of oystershell power.
