Hormiports

The HORMIPORTS project involves the use of Fiber-Reinforced Concrete (FRC) in the manufacture of anti-glare concrete caissons (NOWAVES patent) for vertical piers.

 

The HormiPorts project aims to reduce traditional reinforcement and the thickness of certain sections, resulting in a lighter and more slender structure, as well as shorter construction times.

 

To develop the project, various caisson designs (standard and anti-reflective, with square and circular cells) were modeled using both traditional concrete and reinforcement as well as fiber-reinforced concrete, and several different types of fibers were tested. It was found that the longest fiber with double anchoring exhibits greater mechanical capacity, and its effect is more significant the thinner the section. Based on these results, it was concluded that the use of fiber-reinforced concrete (FRC) in square-cell marine caissons is feasible.

 

The test conducted showed that the fiber could completely replace the rebar in certain areas of the caisson. This solution offers several advantages: a cost reduction of 2.5–3.5% in the manufacture of the walls, despite the high price of the metal fiber studied; shorter construction times; improved durability due to the fibers’ crack-containment properties; and better performance against impacts or point loads.
