In this study, the workability and mechanical properties of Fiber Reinforced Self-Compacting Lightweight Concrete (FRSCLC) were investigated. Concrete samples were produced with steel fiber to which low and high carbon were added. The fluidity of FRSCLC was conducted with two categories of flow ability; the property and viscosity of fresh concrete. The mechanical performance of the concrete mixes was determined with short and long-term tests, which include compressive and flexural strength at 3, 7, 28 and 365 days. The test results showed that adding fibers to self-compacting lightweight concrete mixtures decreases workability. On the other hand, compressive strength was less enhanced, compared to the results of flexural strength. As a result, the compressive and flexure strength of SCLWC's increased up to 30% and 43%, by adding fiber at 28 days, respectively.
