Abstract:
Six reinforced concrete beams, each with a large rectangular opening, were severely damaged during a test program. These beams were then repaired: loose concrete was removed and replaced with epoxy mortar and the cracks were filled by epoxy injection. The repaired beams were then tested in the same manner as the original beams. A comparison made between the two sets of test data shows the effectiveness of the repair technique. *
