Influence of aggregate type and size on properties of pervious concrete
Highlights A standard dense concrete mixture and four pervious concrete mixtures were studied. A higher amount of small aggregate fractions yielded higher density mixtures. A higher amount of small aggregate fractions yielded greater flexural strength. Connected porosity was influenced more by the aggregate type than the size. Pervious concrete can be used as concrete block paving.
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 4–8mm to 8–16mm aggregate fractions (30:60 or 60:30). The results suggest that a higher amount of small aggregate fractions (4–8mm) 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.
