The compressive strength of concrete is typically between 20 and 40 MPa (3000 and 6000 psi), while the flexural strength is typically between 3 and 5 MPa (400 and 700 psi). These strengths are enough to support a wide variety of loads without breaking. In order to avoid breaking, a beam's compressive and flexural strengths must be equal.
