| Summary: | Fibre Reinforced Polymer (FRP) offers a great potential in reinforced concrete construction
due to its corrosion and chemical attack resistance, high strength to weight ratio, ease of
handling etc., and makes it suitable as an alternative material to potentially replace steel
reinforcement used in conventional concrete construction. The performance of plain glass
fibre reinforced polymer (GFRP) mounted at the outer tension surface of beams or known as
near surface mounted (NSM) technique, with some bonded lengths and groove sizes was
investigated for bonding strength, ultimate load and the influence of bonded lengths and
groove sizes, by using pull-out bending test. Six specimens were reinforced with 12.5 mm
diameter (d0) of plain GFRP, and four bonded lengths which equal to 6d0, \2db, 18*4 and
24db with three groove sizes of 16 mm, 19 mm and 25 mm were tested in this study. From the
findings it shows the average bonding strength decreases when the bonded lengths is
increased and vice versa for the ultimate load, while the ultimate load tends to decrease when
the groove size is increased. |
