What Is The Characteristic Strength Of Concrete? - [Civil ...

The characteristic strength of concrete is the result of the compressive strength of the concrete cube test. 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.
