Think of structures in the construction of wharfs, sea walls, wave breakers and water treatment plants. What are the challenges that can interfere with the success of such projects? First, we must consider the impact of chloride ions which can cause corrosion. Second, it’s crucial to assess the risk of water tension on the structure and determine its tensile strength. Finally, the last challenge consists of the handling of the materials while the structure…
