Keywords: FRPC; CFRPC; GFRPC; AFRPC; Rehabilitation; Strengthening 1. Introduction Advanced composite materials have found expanded use in aerospace, marine and automobile industries during the past few decades (1960 onwards) due to their good engi￾neering properties such as high specific strength and stiff- ness, lower density, high fatigue endurance, high damping and low thermal coefficient (in fiber direction), etc. Recently, civil engineers and the construction industry have begun to realize potential of composites as strengthening material for many problems associated with the deteriora￾tion of infrastructures. Over the last decade, an increase in the application of FRPCs has been seen in construction industry because of their good engineering properties. Fur￾ther, these are being considered as a replacement to the conventional steel in reinforced concrete structures due to continuing drop in the cost of FRPC materials. Various aspects of FRPC materials including guidelines for selec￾tion of polymer adhesives for concrete have been high￾lighted by ACI Committee-503 [1] and Uomoto et al. [2]. Issues related to selection of materials have also been dis￾cussed by Karbhari [3]. Einde et al. [4] and Bank et al. [5] have presented a summary of applications of FRPC mate￾rial in civil engineering whereas general design guidelines for FRPC application can be found in Bakht et al. [6], ACI Committee 440 [7] and Nanni [8]. Use of FRPC sheets for strengthening and rehabilitation of concrete structures has attracted considerable interest [9–12]. First applications of composites were in the form of rebars and structural shapes. Later, FRPC laminates were used for strengthening of concrete bridge girders by bonding them to the tension face of girder [13] as well as for retrofitting of concrete columns [14]. FRPC are available in the form of rods, grids, sheets and winding strands. Review of literature up to 1996 can be found in ACI Committee 440 [15]. Another general review on class of materials including FRPCs used in civil construction was presented by Bakis et al. [16]. They divided the whole review into structural shapes, internal reinforcement, externally bonded reinforcement, bridge, standards and codes. A review on shear strengthening of RC beams with FRPCs was done by Deniaud and Cheng [17], Bousselham and Chaallal [18]. Review related to the bond-slip model for FRPC sheet/plate bonded to concrete have been presented recently by Lu et al. [19] and review for upgrading of beam-column joints with FRPC can be found in Engindeniz et al. [20]. A large volume of literature 0263-8223/$ - see front matter 2007 Elsevier Ltd.
