The focus of the former studies have been to securing appropriate pores applicable to the aquatic environment and extracting an optimum mixture which satisfies the required strength of concrete as a structure by substituting pumice stone for crushed stones used to manufacture porous concrete. However, the lack of research has been evident on the water purification performance of each optimum mixture derived from applying appropriate pores to the aquatic environment. Therefore, this study intends to compare and analyze the water purification performance of the respective optimum mixtures derived in the previous studies. According to the experimental results, it represents that the porosity or pumice stone content of porous concrete has no effect on the items of pH and DO. In the experimental results of SS, BOD, COD, T-N and T-P, their common removal efficiency was found to be higher at the design porosity of 10% than 5%. Based on the results of permeability test at the design porosity of 5%, their removal efficiency was shown to be low because continuous pores were not formed properly. By examining these issues , it is evident that if a mixture of 5–13mm crushed aggregate, 10% porosity and 10% pumice content is applied to the aquatic environment, the porous concrete can satisfy the conditions for securing appropriate pores, the required strength of concrete as a structure, and the water purification of the mixture at the same time.
