ASTM C39, Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens, specifies that the loading rate fall within 0.14 to 0.34 MPa/sec (20 to 50 psi/sec). On average, the compressive strength of cylinders tested at the high load rate limit will be 3% greater than cylinders tested at the low load rate limit.

For example, for lower strength concrete, the strengths of 150 × 300 mm and 100 × 200 cylinders are almost the same [115], [122], although some researchers found a difference in compressive strengths even for lower strengths [123]. For higher-strength concrete there is an observed size effect [95], [98], [115].
