What is meant by "Characteristic strength" (fck) of concrete??

Jan 04, 2013· From the graph we can clearly say that 30 MPa is the characteristic strength of the given concrete mix. The value of fck is lower than fcm (40 MPa mean strength) by σ, where σ is the standard deviation of the normal distribution. So we can say the given concrete mix has a characteristic strength of 30 MPa or it is a M30 grade mix. M Mix
