Compressive Versus Flexural Strength. Compressive strength refers to the maximum amount of compressive or crushing load concrete can bear before failing, which basically means how much weight or force the concrete can withstand without breaking or cracking. Concrete has enormous compressive strength that increases as the concrete ages.
