Glass fibre reinforced plastic (GFRP) rebars for concrete structures

The study described is a part of a large-scale experimental and theoretical programme on the application of fibre reinforced plastic () reinforcement for concrete structures initiated at the Université de Sherbrooke (Sherbrooke, Canada). The programme is being carried out to gain an insight into the flexural behaviour of concrete beams reinforced with glass fibre reinforced plastic () rebars. Results of experimental study on 3.3 m long beams reinforced with two different types of rebars are presented and compared to that of conventional steel reinforced concrete beams. Three series of reinforced concrete beams were tested in flexure. The beams were 200 mm wide and respectively 300, 450 and 550 mm high. The paper also attempts to present the properties of and its components and to give an oversight of relevant research activities involving rebars as reinforcement for concrete units.
