Abstract

Self-Compacting Concrete (SCC) is a highly workable concrete that can flow throw densely reinforced or complex structural elements under its own weight and adequately fill voids without segregation or excessive bleeding without the need for vibration. Concrete is strong in compression but weak in tension. To make it strong in tension discontinuous Anti-Crack high Dispersion glass fibers are added to it. SCC made with addition of discontinuous glass fibers is called as Glass Fiber reinforced Self Compacting Concrete (GFRSCC). In this paper an experimental study has been carried out to check the effect of Anti-Crack high Dispersion glass fibers on the split tensile strength of SCC. The Normal SCC was made by replacing 25% of the total cement by Fly Ash and 5% by Ground Granulated Blast Furnace Slag (GGBS). For GFRSC, the Cem-FIL Anti-Crack High Dispersion glass fibers were added by the percentage weight of total cementitious material. The fibers were added in two percentages like 0.25% and 0.50% by the weight of total cementatious material. The cylinders of size 100mm diameter and 200mm height were cast for the split tensile test. After the test, the results shows that, the addition of 0.25% and 0.50% glass fibers increases the split tensile strength by 5.9% and 13.18% respectively compared to the split tensile strength of Normal SCC. By addition of 0.25% glass fibers the workability of SCC was not affected and for 0.50% addition the workability reduces to some extent.
