The mechanical properties of traditional pervious concrete are insufficient, which limits its application. In view of the imperfections of traditional permeable concrete in mechanics, this paper aimed to find a suitable material composition that can be used as a feasible mix design of high-performance pervious concrete, to essentially improve its mechanical properties. Samsung planned for the production of high performance concrete, the concrete mix design was targeted to be 15 MPa higher for G40 concrete and below, and 20 MPa for G60 concrete and above. This strategy was incorporated into the concrete mix design in order to allow for the potential of strength loss in the production process at the batch plant, or
