3D reconstruction in the context of cement and concrete involves the creation of a three-dimensional digital model of existing concrete structures or elements. This process is crucial for various applications, including structural analysis, damage assessment, and heritage preservation. 3D reconstruction enables detailed visualization and analysis, allowing engineers and researchers to understand the current state of concrete structures and plan necessary interventions. It plays a significant role in the maintenance and rehabilitation of infrastructure, especially in environments subjected to severe conditions that can accelerate deterioration.
