Abstract: The strength properties and other important parameters regarding the behavior of epoxy repaired concrete walls during fire exposure are experimentally determined. Both ASTM E-119 and the SDHI time-temperature pseudo fire exposures are considered in evaluating the fire ratings of epoxy-repaired concrete walls. Conclusions are provided regarding the inter-relationship between fire performance and wall thickness, crack width, duration and intensity of fire exposure and the type of epoxy adhesives.
