Abstract To study the relationship between the anti-penetration performance of early-strength concrete and the curing age, the 35 mm ballistic gun and 35CrMnSiA reduced-ratio ogive-nose projectiles were used to conduct penetration experiments on the ultra-early-strength concrete named “UR50” under two curing periods. According to the experimental data, the penetration response characteristics of ultra-early-strength concrete at two curing ages were compared and analyzed. In order to further study the response mechanism of projectile penetrating ultra-early strength concrete, the response model of rigid projectile penetrating semi-infinite target is introduced for theoretical research, and the improvement of the penetration resistance of special steel fiber in ultra-early strength concrete is analyzed by using the Berezan formula. The experimental results show that the process of projectile penetrating ultra-early strength concrete target at low speed can be divided into two stages: impact cratering and stable penetration. The ultra-early-strength concrete can achieve the anti-penetration performance of 28 days after curing for 7 days. The response model of rigid projectile penetrating semi-infinite target was used to compare the predicted penetration depth with the experimental penetration depth of ultra-early-strength concrete with one dimension for 7 days and 28 days, and it was found that the maximum relative errors were 29.13 % and 8.48 %, respectively. The calculated unconfined compressive strength of ultra-early-strength concrete at two ages in the response model was corrected to make the calculated penetration depth conform to the actual results.

Key words： UR50 ultra-early-strength concrete rigid projectile penetration penetration depth theoretical model
