Abstract: Self compacting concrete (SCC) is emerging technology in the construction industry. SCC has the ability to flow and fill the formwork without using any external vibrations. In this study, fresh properties of ternary blended SCC using fly ash (FA) and alccofine (AF) are investigated. In this study, SCC mixes are manufactured in two categories. In the first category, the replacement level of FA was kept at 30% for all concrete mixes with varying dosages of AF (0%, 5%, 10% & 15%). In the second category, the replacement level of mineral admixtures (FA and AF) was kept at 35% with varying dosages of AF (0%, 5%, 10% & 15%). SCC fresh properties were investigated using slump flow, V-funnel & L-box tests. From the first and second category test results, it is observed that the optimum replacement of alccofine can be taken as 10%.
