1992-1-1 In Eurocode, all design equations use f_ck, and this is defined as the 'Characteristic compressive cylinder strength at 28 days'. The reason I believe it has both in the designation for the strength class is simply to cover that in some regions where Eurocodes are applicable concrete may still be specified, manufactured and tested based on the cube strengths.
