MECHANICAL AND FRESH PROPERTIES OF FIBER REINFORCED SELF-COMPACTING LIGHTWEIGHT CONCRETE

In this study, workability and mechanical properties of fiber reinforced self-compacting lightweight concretes (FRSCLC) were investigated. Concrete samples were produced with steel fiber include low and high carbon were added. Fluidity of FRSCLC has been conducted by two categories of flow ability property and viscosity of fresh concrete. 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 decreased workability. On the other hand, compressive strength was lower enhanced compare to the results of flexural strength. As a result, compressive and flexure strengths of SCLWC’s increased up to 30% and 43% adding fiber at 28 days, respectively.
