Abstract:
This article provides a brief background of sprayed fiber reinforced polymer (SFRP) composite materials for structural rehabilitation and summarizes experimental results characterizing the strength, stiffness, and toughness of the material. Such a lay-up procedure is inexpensive, versatile, rapid, easy to apply, and requires relatively little preparation of the surface to be repaired. SFRP materials were observed to enhance the strength, toughness, and deformation capacities of plain concrete beams. In particular, SFRP was observed to fully rehabilitate deteriorated concrete beams. Factors affecting the quality of the final product are also discussed.
