    What Is The Characteristic Strength Of Concrete?

    The design strength is the required strength of concrete to be designed as per the IS code. For example, assume that the strength of concrete required M25, and the target design strength is 28.5 N/Sqmm. Now the chances of failure of concrete cubes fail at 25N/Sqmm is only 5%. The design strength is 28.5 N/Sqmm, and the characteristic strength of concrete is 25 N/Sqmm
