Abstract

To elucidate the mechanism underlying the changes in the bonding performance of reinforced reef limestone concrete under dry–wet carbonation cycles, and to establish a foundation for its durability analysis and design, experiments were conducted with varying dry–wet carbonation cycles (0, 20, 40, 60, and 80 cycles) and loading rates (0.01 mm/min, 0.1 mm/min, 1 mm/min, 2 mm/min, and 5 mm/min) through pull-out tests. The results demonstrate that as the number of dry–wet carbonation cycles increases, the damage to reinforced reef limestone concrete intensifies progressively, reaching a mass loss rate of 3.05% by the end of the cycles, while the ultrasonic wave velocity decreases by 17.4%. The effects of different loading rates and cycle counts on reinforced reef limestone concrete are primarily observed through alterations in peak bond stress. Utilizing the experimental data, this study established an equation to analyze the influence of dry–wet carbonation cycles and loading rates on the bond strength and slip behavior between steel bars and reef limestone concrete. This equation offers a theoretical framework for the durability analysis and design of reinforced reef limestone concrete.

Keywords: dry–wet cycle; concrete; center pull-out test; bonding strength
