Abstract:
Non-corrosive and lightweight materials like fiber reinforced polymers (FRPs) are fast replacing steel as a material of choice in rehabilitation projects. All research to date has focused, however, on FRP wraps and jackets with continuous, unidirectional fibers. In this article, an entirely new method of repair using Sprayed Fiber Reinforced Polymer (SFRP) coatings is described. This aritcle describes the spray process and compares the laboratory performance of the spray to traditional FRP wrap in the context of full-scale reinforced concrete bridge girders.
