Abstract |
In this study the influence of steel fibers on workability and compressive strength of self-compacting concrete(SCC) was investigated. Steel fibers were added to concrete in five different volume percentages of 0, 0.5, 1.0, 1.5, and 2.0 by volume of concrete, respectively. The water-to-binder ratio was kept constant at 0.41. Fresh concrete behavior was evaluated by means of J-Ring test, slump flow test, V-funnel test and U-box test while the hardened concrete behavior was evaluated by means of compressive strength test. Test results show that the workability of fresh concrete with 1.5% and 2.0% of steel fibers decreased sharply, which cannot meet the requirement of SCC. After 90 minutes, the fresh concrete mixed with steel fibers had lost its high flow characteristics by J-ring test and slump flow test. The compressive strength of concrete with steel fibers is higher slightly than that of concrete without steel fibers. Based on the results, steel fiber added in producing SCC is possible and 1.0% steel fiber was recommended to be considered as the optimum amount.
