The Port of Rotterdam Authority conducts a trial with geopolymer concrete in the Eemhaven, marking the first application of this cement-free concrete in a maritime setting. Geopolymer concrete, devoid of traditional cement, exhibits a 50% reduction in CO2 emissions, aligning with the Port Authority’s commitment to environmentally conscious port development. This innovative approach involves the use of reinforced geopolymer concrete in a saltwater environment, replacing cement with an alternative binder to achieve significant emissions reduction.
As part of its sustainability initiative, the Port Authority aims to replace certain quay walls, maintaining 80 kilometers of quay walls and 200 kilometers of slopes. Developed with ‘Innovative Sqape technology – SQAPE,’ the geopolymer concrete mix was tested by pouring formwork for a quay wall structure and beams during the trial. Looking ahead, the Port Authority plans to implement this environmentally friendly concrete in a quay wall at the Tweede Petroleumhaven by the end of 2023, monitoring its performance over the subsequent years. This trial not only reflects the Port Authority’s commitment to reducing its CO2 footprint but also serves as a valuable learning experience for the practical aspects of working with geopolymer concrete, contributing to the long-term goal of sustainable port infrastructure.
