The mix design of the pervious concrete is shown in Table 3. The required amounts of cement, water and coarse aggregates were calculated and weighed separately on an electronic balance with a minimum count of 0.1 mg, based on the A/C and W/C ratios. These ingredients were then added to a 120-L electric concrete mixer.
