Abstract
Self-Compacting Concrete (SCC) is a concrete that has a high flowing ability with no segregation. . SelfCompacting Concrete added with glass fibers create Glass Fiber Reinforced Self-Compacting Concrete (GFRSCC). SelfCompacting Concrete added with Steel Fibers create Steel Fiber Reinforced Self Compacting Concrete (SFRSCC). The present work deals with the workability and strength studies on Glass Fiber Reinforced Self Compacting Concrete and Steel Fiber Reinforced Self Compacting Concrete of grade M30 with GGBS. The mix proportions for Self-Compacting Concrete were arrived at by performing mix design and then fine-tuning using EFNARC guidelines. In the past, several studies have been carried out on the SCC with addition of fibers. In this study, addition of four different volume fractions of glass fibers and steel fibers viz. 0.2%, 0.4%, 0.6% on a M30 grade SCC was investigated. For testing the properties of SCC and Glass Fiber Reinforced SCC (GFRSCC) in fresh state, Slump-flow, L-box and V-funnel and U-box tests were conducted. Whereas for testing the properties in hardened state, Compressive Strength, Split Tensile Strength, Flexural Strengths and durability tests were planned to be carried out for 7days and 28days. In this paper, the results obtained on the fresh and hardened properties of SCC with and without fibers are presented
