Impact experimental results for concrete targets and the factors influencing target behaviors in four velocity ranges were presented in order to evaluate the impact resistance of concrete. Two types of velocity partition means were concluded and four velocity ranges were suggested based on material dynamic responses and apparent penetration behaviors. The experimental studies were reviewed from low velocity to hypervelocity. In low velocity range(impact velocity within 40 m/s), failure modes of beams, columns, slabs and shells were briefly summarized. In medium velocity range(impact velocity between 40 m/s and 1 km/s), the effects of relative diameter of missile to target, coarse aggregate, uniaxial compressive strength and steel bar on the thick target penetration were discussed. In high velocity range(impact velocity between 1 km/s and 2 km/s), the semi-hydrodynamic transition velocity and cratering effects were introduced. In hypervelocity range (impact velocity over 2 km/s), the density-dominant hydrodynamic penetration phenomena were described. Some research proposals on concrete penetration were given for the further study.
