As a result of Akçansa’s long-term R&D studies, concrete using the ‘1803 Cement’ product has been developed to have a minimum service life of 100 years. 1803 Concrete, specially designed for the 1915 Çanakkale Bridge project, has been produced with the feature of processability in a record time of 6 hours in order to adapt to casting conditions at sea. In addition, in the shaft fabrications at the junction detail of reinforced concrete foundation and steel legs, it was ensured that the self-settlement feature was maintained for 6 hours.
