Pervious concrete, which has pores to allow permeation of water and air, is being used as one of the solutions for combating the problems induced by urbanization. For the purpose of evaluating the main factors affecting the performance attributes of pervious concrete, a total of 24 pervious concrete groups with varied mortar volumes and water/cement ratios were made for porosity, water permeability and cube strength measurements. Based on the test results and regression analysis, it was found that interconnected porosity plays major role in the water permeability, while the open porosity and W/C ratio are together the key factors governing the cube strength.
