Abstract:
I Concrete Is One Of The Most Widely Used Construction Material. The Present Trend Of The Concrete Technology Is Towards Increasing The Strength And Durability Of The Concrete To Meet The Demands Of The Modern Construction. Now A Day’s Fiber Reinforced Concrete Is Widely Using Because Of Its High Tensile Strength And Fire- Resistant Properties. Adding Fiber To A Concrete Mix Can Reduce Cracks And Increase Impact Resistance. To Reduce The Huge Amount Of Usage Of River Sand In Concrete, Sea Shells Are Using As A Replacement Of Fine Aggregate In Concrete. To Provide An Economical Concrete, Improve The Durability Ofconcrete And Reduce The Demand Of Fine Aggregates. The Present Study Determines The Compressive Strength Of The Concrete When 1% Of Steel Fibers Are Added, By Weight Of Cement And Compressive Strength Of A Concrete When 70% Of Fine Aggregate Is Replaced With Sea Shells. The Study Also Determines The Strength Of Concrete In Combination Of 70% Ofsea Shells Replacement And 1% 0f Steel Fibers Addition. For Experimental Work M25 Grade Concrete Cubs Are Casted And Tested For 7 Daysand 28 Daysstrength. The Conclusion Of Present Study Is The Compressive Strength Of Concrete Will Increase By 86.73% Than Conventional Concrete By 70% Replacement Of Fine Aggregate With Sea Shells And 1% Addition Of Steel Fibers.
