2021-6-21 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

2016-7-7 For normal field applications, the concrete strength can vary from 10Mpa to 60 Mpa. For certain applications and structures, concrete mixes can be designed to obtain very high compressive strength capacity in the range of 500Mpa, usually referred as Ultra High Strength Concrete or Powder Reactive Concrete.
