Abstract

Concrete Is One Of The World Most Versatile And Widely Used Construction Material Due To Its Superior Ability To Be Mould Into Any Desired Shape And Strength. But Concrete Has Relatively Low Tensile Strength, Weak In Tension And Poor Resistance To Expansion Cracking. Thus, Addition Of Enset Fiber Composites As Reinforcement Has Been Introduced To Improve The Properties Of Concrete Such As, Tensile Strength, Flexural Strength, Toughness And Also It Reduces Crack Formation. Cement, Which Is An Essential Concrete Material That Takes Up 10%15% Of The Volume Of The Concrete. Its Production Is An Environmentally Unfriendly Process Due To Release Of CO2 Gas To The Atmosphere. In Addition To This, It Is The Most Expensive Material When Compared To The Other Components Of Concrete. Hence, Alternative Cheap Natural Pozzolanic Cementing Materials Are Of Great Interest To Deal With In Such A Situation. Cow Dung Ash (CDA) Is Cheap Cattle Farming By-Products And Possess Pozzolanic Properties. The Primary Goal Of This Study Was To Conduct An Experimental Study Of The Combined Effect Of The Partial Replacement Of Cement By Cow Dung Ash And Addition Of Enset ?Fiber In Concrete Production. The Study Examined The Chemical Composition And Physical Properties Of Cow Dung Ash And Enset ??Fiber On The Workability Of Fresh Concrete, The Mechanical Properties, The Microstructural Analysis Of Hardened Concrete And On The Environmental And Economic Analysis Of Using CDA As A Cement Replacing Material. The Chemical Composition Of Cow Dung Ash Was Examined, And The Summation Of Sio2, Al2O3and Fe2O3 Was 81.08% And Classified As Class F Pozzolanic Material. The Consistency And Setting Time Increase As The CDA Replacement Amounts Increase, But Workability Decreases As Replacement Increases. The Compressive Strength, Flexural Strength And Tensile Strength Of Concrete For C-3 (10% CDA With 0.5% EF) Shows Less Strength At 7th Day Curing Age But Shows Better Improvement On The 28th Day. Microstructure Tests (SEM And XRD) Analysis Including Environmental And Economic Analysis Shows Improved Performance For Replacement Of Cow Dung Ash At 10% With 0.5 % Addition Of Enset Fiber. Therefore, The Maximum Amount Of Replacement Is 10% CDA With 0.5% Addition Of EF, Which Gives Better Strength Properties Of The Concrete.
