SHPB is preferred and used for testing the compressive strength of concrete at high strain rates up to 10 3 s −1 [9]. In concrete SHPB tests, both the inertial of a specimen and end friction on the interfaces between the specimen and pressure bars have considerable effects on the measured concrete strength [33], [34].

Testing High-Strength Concrete Compressive Strength
Testing high-strength concrete (HSC) for compressive strength puts into doubt a certain number of concrete testing practices. First, most testing laboratories are equipped with loading capacity machines inadequate for testing 150 x 300-mm (6 x 12-in.) specimens, thus limiting HSC specimens to 100 x 200 mm (4 x 8 in.) in size.
