The rehabilitation of a concrete structure using fibre reinforced plastics

grantor: University of TorontoCracks in concrete may become significant if they begin to compromise the strength, durability, or aesthetics of a structure. Prior to the undertaking of any repair procedure, the cause of cracking must be established. Typical steps that should be included in a condition survey are outlined to assist in the diagnosis process. As our nation's infrastructure continues to deteriorate, the need for more economical and more durable rehabilitation techniques has emerged. The use of Fibre Reinforced Plastics provides an attractive alternative to traditional rehabilitation techniques. The installation of these light-weight materials is less labour- and equipment-intensive. Fibre composites can also enhance durability as they prevent the passage of chlorides and other harmful chemicals. Finally, composites can considerably reduce the time that structures are taken out of service. Experimental results from short-term tests conducted on walls and beams indicate the effectiveness of carbon and glass composites for rehabilitating damaged structures.M.A.Sc
