Abstract

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.
