concrete having the compressive strength class of C25/30 at the age of 28 days, mix cured and the compressive strength is determined on cubes with the sizes of 150 mm will have a mean compressive strength instead of the above calculated f
The maximum load in pounds supported by the block before failure occurs, divided by the area in square inches, shall be taken as the compressive strength of the block. The arithmetic mean of the compressive strengths of the five blocks shall be taken as the compressive strength of the blocks for the purpose of Clause 10 of this specification.
Concrete strength has many terms such as minimum strength, characteric strength, target strength etc. Both should be viewed separately. As the masonry blocks are made of concrete it does not imply that the whole specifications of concrete are applicable.
