Abstract
Experimental test results obtained from fire tests on small-scale, intermediate-scale, and large-scale epoxy repaired shear wall specimens are presented. The specimens were fabricated from ready-mixed concrete using a six-bag mix. The shear wall specimens were cured for approximately seven days prior to the formation of the crack. Six different structural epoxy adhesives were considered. All six are thermosetting resins derived from the oil refining intermediate products, epichlorhydrin and bisphenol A. Fillers were not added to the adhesives either before or during the injection of the adhesives into the cracks. These six epoxy adhesives were chosen because their chemical and physical properties are representative of most epoxies that have been or are being used for the repair of damaged structures since the 1971 San Fernando Earthquake. They have been divided into two groups: low viscosity and high viscosity epoxy adhesives.
