For 12.5-mm washed-MSWIBA pervious concrete mixes with
w/c ratios of 0.30–0.50 and pore-filling paste ratios of 40–
80%, the connected porosities, permeability coefficient, and
compressive strength were 10.3–32.7%, 0.6–4.1 cm/s, and 4.8–
12.7MPa, respectively. These results are consistent with the
results of previous research on pervious concrete made with
natural aggregates and indicate that 12.5-mm washed-
MSWIBA pervious concrete can satisfy practical engineering
requirements for pervious concrete. Therefore, using washed
MSWIAB as the aggregate in pervious concrete is considered
practical.
