Fctk c25/30
WebJan 7, 2024 · In the Model Code the relation fck = fcm - 8 (MPa) is given. This means a coefficient of variation for a concrete C25 of v = 0.15 and for a concrete C90 of v = 0.05. In combination with Br = 0.13 for the punching tests this would mean an increase of the coefficient 0.116 of about 6.8 % for C25 and 3.6 % for C90 (see [14, p. 91).
