Description
Summary:Potential use of short and long fibers blends in a concrete may enhance the properties at micro and macro scale of composite. The idea of combining the short length and long length fibers with different volume proportions to form Graded Fibers. It would aid in the prevention of micro and macro cracks, enhancing concrete’s pre- and post-peak performance. The effect of adding Graded Glass Fibers with varying fibre lengths and volume fractions to Glass Fiber Reinforced Concrete is investigated in this work. The tests were carried out using M40 concrete with a 0.20 percent fibre volume. It contains Single length Glass fiber in Mono Fiber form (150 µm, 6 mm length and 20 mm length fiber), short length Glass fiber in Graded form (150 µm Micro length Glass fiber+6 mm SLGF) and LLGF in Graded form (150 µm Micro length Glass fiber+6 mm SLGF+20 mm LLGF). This study found that Graded GFRC had a greater post-peak energy absorption capacity than Mono Glass Fiber Reinforced Concrete.
