Abstract: A total of 50 repaired and unrepaired reinforced concrete slab specimens were tested under static and cyclic loading conditions in this study. The specimens were of rectangular cross-section, 300 × 80 mm, and tested in flexure, simply-supported on a span of 600 mm under a line load at mid-span. Four types of specimens were tested. These include control specimens, which were unrepaired, and three other types of repaired specimens with cover reinstatement up to: the level of the reinforcing steel; mid-depth of the reinforcing steel; and full depth of the reinforcing steel, respectively. The performance of specimens statically-loaded to failure was monitored, while the deterioration of flexural rigidity of specimens subjected to cyclic loading was evaluated after being subjected to a predetermined number of cycles at various stress ranges. The results of experimental tests are summarized and discussed in this paper. © 1995.
