Abstract: In this research, the hammering test method was employed to estimate the dynamic elastic modulus and void ratio of the natural transverse and longitudinal frequency for pervious concrete (PEC, porous concrete). The relationships between the natural frequencies, elastic modulus, and void ratio of PEC are examined and analyzed. Based on the experimental results, it was clarified that the natural frequencies measured via hammering test are negligibly affected by both the impact surface roughness of PEC and the impact force of the inspection hammer. Instead, the natural frequencies are more significantly affected by the void ratio of PEC. The results also found that the relationship between the natural frequencies and void ratio can be approximated using quadratic functions, while the relationship between the dynamic elastic modulus and void ratio of PEC can be approximated with linear functions. Overarchingly, the results and analyses confirm that the hammering test is an accurate method for evaluating the void ratio and elastic modulus of PEC.
