ACCIONA will use more than 48,000 tonnes of low-carbon concrete, manufactured with type CEM III/A cement, to build the caissons that will expand the new Container Terminal at the Port of Cádiz.

The cement used to produce this concrete is HOLCIM’s ECOPLANET III/A 42.5 N/SRC. It is ideally suited to the construction of port caissons, as it delivers the strength development required for sliding while supporting sustainable construction (it incorporates recycled materials and requires less energy to produce).

More durable, lower-maintenance structures

This material helps to produce more durable, lower-maintenance structures. The use of sustainable concrete significantly reduces CO₂ emissions and contributes to extending the service life of port infrastructure.

Exceptional dimensions

The €54 million contract provides for the extension of the current 510-metre quay to 1,100 metres, reaching a total yard area of 40 hectares for container traffic. To achieve this, eight reinforced-concrete caissons will be built, each more than 63 metres long, 24 metres wide and 20.5 metres deep—roughly the height of a seven-storey building.

This project is expected to strengthen the port’s logistics capacity and operational efficiency, while boosting local maritime trade. It reflects ACCIONA’s strong commitment to sustainable development and the continuous improvement of port infrastructure.
