Abstract:
The efficacy of ultra-high performance concrete (UHPC) overlays holds great promise for mitigating chloride-induced corrosion in reinforced concrete bridges. This research examines the corrosion resistance of a bridge structure through the application of simulation techniques to better understand the effectiveness of ordinary concrete and UHPC overlays. To represent the three-dimensional microstructure of ordinary concrete and UHPC, the Virtual Cement and Concrete Testing Laboratory (VCCTL) program is utilized. Additionally, an agent-based model is developed to investigate chloride penetration mechanisms within the concrete overlays. Furthermore, the structural response of the overlayed bridge under a corrosive condition is studied.
