Abstract

This paper presents an experimental work for evaluating the flexural failure behavior of a con- crete beam repaired by crack injection techniques. Not only flexural strength but also tension softening dia- grams and fracture energy were used for the indices. In addition, a size effect on the flexural strength of the repaired specimens, which is larger than that of original concrete (plain concrete), is observed experimentally. Then the importance of evaluating the cracks in repaired specimens is indicated.
