The effects of replacing sandstone with incineration bottom ash and different water-to-cement ratios and
aggregate sizes in pervious concrete bricks preparation were investigated. Among the various permeable
brick specimens, the compressive strengths of 11 different mix proportions exceeded that of traditional
red bricks (by 14 MPa), and was maximum for the specimen with bottom ash aggregate size #4 and a
water-to-cement ratio 0.55. The permeability coefficients, although smaller than that of general pervious
concrete, were within general permeable pavement specifications (102 cm/s). Therefore, it is recommended
for general bicycle ways, sidewalks, and landscaping, not roads with high traffic flow.
