The structural applications of fiber reinforced polymers are described in this elaborative book. Fiber reinforced polymers are an extremely significant and widely utilized form of material. These materials exist primarily due to the emphasis given to petrochemical and non-petrochemical products. These polymers are economical and more widely used as compared to natural polymers. The field of fiber reinforced polymers is an evolving and growing field of research due to its special properties and traditional and modern applications. This book discusses the improvement in environmental aspects, important areas of research and potentials of fiber reinforced polymers in civil construction and concrete repair.
