This work presents factors affecting bond strength between SCC and old concrete. Cylindrical specimens (150 × 300 mm) have minimum coefficient of variation. Roughness of substrate concrete has a significant effect on bond strength. Composition of SCC have a significant effect on bond strength. Prism specimens represent more reliable bond strengths.
