In this study, five different concrete mixtures were prepared. The first one was a
standard dense concrete mixture, while the others were pervious concrete mixtures
with two different types of aggregates and different proportions of aggregate fractions
(Table 1). Crushed dolomite stone was used as a natural material, and steel slag
from Croatian landfills near the town of Sisak was used as a substitute aggregate
material. The relevant properties of the aggregates are given by Netinger et al.
