•Strain acceleration and geometry of a specimen lead to inertia effects in SHPB test.•Concrete SHPB tests were performed.•DIF considering the pure rate effect was proposed.•Proposed DIF provided an accurate prediction for the apparent dynamic strength. The dynamic increase factor (DIF) has been wide...
