The SI unit for concrete strength measurement is the Mega Pascal, although 'Newtons per square millimetre' is still widely used as the numbers are more convenient. Thus 'Fifty Newton concrete,' means concrete which has achieved 50 Newtons per square millimetre, or 50 Mega Pascals.

344 Mishuk Bhattacharjee et al: Effect of Aggregate Properties on the Crushing Strength of Concrete greatly affected by the properties of fine and coarse aggregates (Ayubet al 2012; Joseph et al 2012) [9] [10]. There are some other properties, not dependent on parent
This paper studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test. And the test results show that concrete made from black stone has the highest workability followed by shingles stone brick khoa of aggregates.
Question: Before placing the concrete for the last pier of a drilledpier foundation job, the foreman decided to add water to the ready mix truck. The inspector didn't like the looks of the watereddown concrete and took test cylinders that represented that one pier. The specifications call for a 28day strength of 3000 psi.
The compressive strength of concrete is measured by crushing cylindrical concrete specimens in compression testing machine.
