Capping Concrete Specimens For Compression Testing; In "High strength concrete" in buildings, 56 or 91-day compression test results are sometimes adopted instead of 28-day compression test results. Why? In concrete compression test, normally 150mm x150mm x150mm concrete cube samples is used for testing.

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].
