A Simple Guide to Concrete Cube Testing

The concrete minimum compressive strength will be specified by the client/designer in a specific format. An example of this is given below: C40/50. The 40 is the compressive requirement of 40 N/mm² of a crushed 100m concrete core and the 50 is a compressive requirement of 50 N/mm² for a crushed concrete cube.
