Abstract: Self-Compacting Concrete (SCC) is able to flow under its own weight and completely fill the formwork, even in the presence of congested reinforcement, without any compaction, while maintaining homogeneity of the concrete. Majority of concrete cast rely on compaction to produce good quality concrete. However, compaction is difficult to be done in conditions where there are dense reinforcement and large casting area. Usage of SCC will overcome the difficult casting conditions and reduce manpower required. Addition of fibers will enhance the tensile strength & reduce cracking. SCC will be added with relatively short, discrete, and discontinuous glass fibers to produce Glass Fiber Reinforced Self Compacting Concrete (GFRSCC). The purpose of this study is to investigate the workability and mechanical properties of conventional SCC and GFRSCC. Conventional SCC and GFRSCC samples will be prepared. The laboratory testing included slump flow test, U-Box test, Vfunnel test, Compressive strength test, Split tensile strength test & Flexural strength test. After the tests, results were compared and 0.75% fiber dosage has been proven to be optimum for flexural and compressive strength.
