ACCIONA uses sustainable concrete in the expansion of the Port of Cadiz

• The use of sustainable concrete significantly reduces CO₂ emissions and helps extend the life of the infrastructure

ACCIONA will use more than 48,000 tons of concrete with a low carbon footprint, made with type IIIA cement, to build the caissons that will expand the new container terminal at the Port of Cadiz.

The cement used to produce this concrete is HOLCIM’s ECOPLANET III/A 42.5 N/SRC. This material is ideal for the construction of port caissons, since it provides the required evolution of resistance to sliding, while at the same time promoting sustainable construction, since it incorporates recycled materials in its composition and requires less energy consumption. In addition, this material favors the construction of more durable and less maintenance-intensive structures.

The use of a type III/A cement makes it possible to reduce the clinker content - the component that emits the most CO₂ during the production of concrete - by between 36% and 64%, thanks to the addition of other components such as blast-furnace slag. This translates into a reduction in CO₂ emissions of around 27% compared to sectoral data.

KEY ASPECTS

The 54-million-euro contract includes the expansion of the current 510-meter quay to 1,100 meters, giving a total quay area for container traffic of 40 hectares. Eight concrete caissons will be built, each measuring more than 63 meters long, 24 meters wide and 20.5 meters deep, equivalent to the height of a seven-story building. The aim is to increase the port’s logistical capacity and operational efficiency, as well as to promote local maritime trade.

This project reflects ACCIONA’s strong commitment to sustainable development and the continuous improvement of port infrastructures.
