Definition of Concrete MPa | Hunker
A megapascal (MPa) is a measure of the compressive strength of concrete. It lets inspectors know how much pressure can be applied to the concrete before it cracks or fails. One MPa is equal to one million pascals (Pa); as a pascal is one newton of force per square meter, a megapascal is one million newtons per square meter.

STRENGTH OF CONCRETE - Concrete Sask - SRMCA
WHAT IS FLEXURAL STRENGTH? It is the ability of a beam or slab to resist failure in bending. It is measured by loading unreinforced 150x150 mm concrete beams with a span three times the depth (usually 450mm). The flexural strength is expressed as “ Modulus of Rupture” (MR) in MPa. Flexural Strength is about 12 to 20% of compressive strength.
