Self-compacting concrete (SCC) is a high performance concrete characterized by better workability, its ability to flow under is own weight, completely filing the formwork without any segregation or bleeding and consolidation without the need of vibration. It is more desirable to use in concreting as it can be used in more complex molds, in congested reinforcement and lean structures due to the high early strength gain , lower construction time and costs. Hence, the use of Self-Compacting Concrete (SCC) has a tremendous acceptance in the construction industry and hence requires extensive research. The objective of this paper presents the details on the experimental investigation of finding the effective use of Class C Fly Ash in Glass Fiber Reinforced Self-Compacting Concrete (SCC). Mixtures with the inclusion of Glass Fibers (GFs) and containing FA at replacement rates of 0%, 20%, 40%, 60% cement mass were prepared. Fresh Properties were determined by Slump Flow, T50 cm Slump Flow, V Funnel and L Box Apparatus and its corresponding hardened properties of Compression strength, Split tensile strength and Flexural Strength were determined. Results showed that the best properties of GFRSCC was obtained when FA was added at a replacement rate of 40% cement mass.
