Self compacting concrete (SCC) is one of the emerging technique in concrete technology, which is developed as a solution for areas where placement and compaction of concrete is difficult. One of the salient features of SCC is the usage of higher amount of powder content which is achieved by the usage of mineral admixtures. The glass fiber addition in SCC is a mean to control the early shrinkage cracking in SCC due to higher powder content and also it improves the flexural strength and tensile strength of concrete. The present study aims at a comparison of fresh and hardened properties of SCC with 0.025%, 0.05% & 0.075% (by volume of mix) addition of glass fiber. A combination of the Fly ash (30% replacement of cement) and Metakaolin (at 10% replacement of cement) used as mineral admixtures. The workability of SCC mixture is analyzed by carrying out Slump Flow Test, L Box Test and V Funnel Test. The compressive strength & split tensile strength value of SCC mix was found to improve with increase in rate of addition of the glass fiber and the maximum improvement is observed for mix having 0.075% of glass fiber.
