In order to study the dynamic compression performance of waste glass powder concrete (WGPC) under high strain rate, the experiment uses the split Hopkinson pressure bar (SHPB) device with 4 increasing strain rates to test the plain concrete and WGPC block with 10% waste glass powder, the dynamic compressive strength, peak strain, stress-strain curve and other characteristics are obtained through this experiment, and the variation rules of these characteristics with the strain rate and the amount of waste glass powder are analyzed. The results show that with the increase of strain rate, the dynamic compressive strength of WGPC has significant strain rate effect; In the multi-group test, the dynamic compressive strength of WGPC reached a maximum of 58.45 MPa, compared with static compressive strength, the increase is 166%, which is close to the strength of plain concrete, indicating that the waste glass powder in concrete is a good substitute for cement under high strain rate.
