Calcium profiles measured on concrete cores collected from the 15 blocks placed at the Fehmarnbelt exposure site are presented below. The profiles were measured after about two years (735 days) of exposure to the marine environment, and for each type of concrete, two cores were drilled, i.e. one from below sea level and one from the splash zone.
All profiles were measured according to the method described in APM 214, May 1995: Concrete testing – Hardened concrete – Calcium content.
