Abstract
Concrete has a very low fracture energy and due to this, it cracks at very low load in brittle mode. The main objective of this study was to determine the effect of the addition of glass fiber on the fracture energy of plain concrete of grade C20/25 and C25/30. The percentage of glass fiber added ranges from 0% to 0.6% by volume with a constant increasing interval of 0.2%. The glass fiber are placed in three layers with equal amount placed at uniform interval. The test is performed according to RILEM TC 50 FMC recommendation following the Work of Fracture Method (WFM). It has been observed that addition of glass fiber increases the fracture energy of plain concrete very significantly and change the failure mode from brittle to ductile.
