  3. Abstract:
  4. Self-Compacting concrete (SCC) is identified as a high performance concrete with the ability of self compaction, using its own weight without any external vibration. SCC is able to fill congested area and voids, even in highly reinforced concrete members whilst it flows without segregation. The fresh properties of SCC such as workability can be determined using different tests including slump-flow, J ring, V-funnel, U box, L box, GTM and column technique. In this paper the effect of different amount of cementitious material, silica fume and W/C ratios on workability and compressive strength of SCC are investigated. The results indicate that the workability of mixtures is reduced by increasing the amounts of cement and silica fume. However, the effect of increasing in the silica fume is significantly more than that of cement. Furthermore, it has been found that the V-funnel test is more capable to measure the workability of SCC comparing to other aforementioned methods
