Fck cyl
WebApr 18, 2016 · The value of fck in EC2 is "Cylinder Crushing Strength" of the the concrete at an age of 28 days and it is on average , about 0.8 x the cube strength. The cube strength of concrete is given as fck, cube in EC2. For example C45 / 55. It is strange that STAAD uses cube strength rather than cylinder strength. I think this is quite confusing. WebAccording to American standard (ACI), fck (characteristics of compressive strength) value for concrete mix 8000 is 8000psi (55.2N/mm2 or 55.2MPa) on cylinder test at 28days after mixing, when tested with 15cm dia and 30cm length of cylinder.
