A project in ConCrete contains multiple beams. All beams have a concrete strength of C30/37 and concrete cover of 35mm. But when printing the Project values, ConCrete prints fck =25kN/mm² and a concrete cover of 30mm. Other parameters may be incorrect as well. The compressive strength and concrete cover are just examples.

Solution
The « Project values » in ConCrete, are the values that are stored as preferences. Not what’s assigned to a certain beam.
So open for example this dialog
. Click on ‘Store’. Reprint the report.
