This study investigates the effectiveness of an integrated repair technique for corroded reinforced concrete (RC) slabs using mechanical surface preparation, steel dowels, supplementary reinforcement mesh, and shotcrete jacketing. Six standard-scale RC slab specimens were tested under static two-point loading: one uncorroded control slab (S01); two corroded unrepaired slabs with steel mass losses of 10.6% (S03) and 16.2% (S02); two repaired slabs at the same corrosion levels (S06 and S05); and one uncorroded slab strengthened with compression-zone jacketing (S04). The results showed that corrosion reduced the peak load by about 14% and resulted in losses in stiffness and ductility. In contrast, the proposed repair technique not only restored the original capacity but also increased the peak load by 71–75% compared with the control slab. Although the repaired specimens exhibited higher initial stiffness, they reached their maximum load at smaller deflections, indicating reduced ductility. Compression-zone strengthening improved the peak load by 30% and enhanced post-peak behavior. No interface debonding was observed, demonstrating effective composite action, and confirming the suitability of the proposed system for rehabilitating corrosion-damaged RC slabs.
