Self-Consolidating Concrete (SCC) Is A Special Concrete That Spreads Under Its Own Weight To Each And Every Corner Of A Formwork Without Any External Means Of Consolidation. Therefore, SCC Is A Good Choice For Many Concrete Structures Where Placing And Consolidation Of Normal Concrete Are Difficult Due To The Complex Shape Of Formwork And Congested Reinforcement. This Paper Reports The Key Fresh Properties Of SCC Incorporating Palm Oil Fuel Ash (POFA) As A Supplementary Cementing Material (SCM). Various SCC Mixtures Were Produced Based On The Water/Binder Ratio Of 0.5 And 0.6. POFA Was Incorporated In Concretes Substituting 0%, 5%, 10% And 15% Of Cement By Weight. The Fresh Concretes Were Tested For The Three Key Properties Of SCC Such As Filling Ability, Passing Ability, And Segregation Resistance. The Filling Ability Was Determined With Respect To Slump Flow, T50 Spread Time, And V-Funnel Flow Time. The Passing Ability Was Measured With Regard To J-Ring Flow. The Segregation Resistance Was Examined By Column And Sieve Tests. Test Results Showed The Slump Flow Decreased But The V-Funnel Flow And T50 Spread Times Increased With Higher POFA Content. In Addition, The Segregation Index And Segregation Factor Obtained From Screen And Column Tests, Respectively, Decreased With Greater POFA Content. These Results Suggest That The Filling Ability And Passing Ability Of SCC Decreased Whereas Its Segregation Resistance Increased With Higher POFA Content. This Is Mainly Attributed To The Increased Plastic Viscosity Of Concrete, As Understood From The Results Of V-Funnel Flow And T50 Spread Tests.
