Title: Influence of aggregate type and size on properties of pervious concrete
Abstract: This study investigates the influence of aggregate type and size on the properties of pervious concrete. Five different concrete mixtures were prepared, including a standard dense concrete mixture and four pervious concrete mixtures with varied aggregate types (dolomite or steel slag) and differing proportions of 4–8 mm to 8–16 mm aggregate fractions (30:60 or 60:30). The results suggest that a higher amount of small aggregate fractions (4–8 mm) yielded higher density concrete mixtures and greater flexural strength. However, connected porosity as a main parameter for estimating pervious concrete efficiency was surprisingly influenced more by the aggregate type than the size.
