Influence of aggregate type and size on properties of pervious concrete
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.
