The paper presents the results of pervious concrete testing, made from natural and recycled aggregates, fractions 4/8 and 8/16mm, with a constant water-cement factor (0.35) and without the participation of mineral and chemical additives. In total, four pervious concrete mixtures were made in which the type of applied aggregate was varied. Compressive strength after 7 and 28 days was tested, and prior to pressure testing, tests were carried out using non-destructive methods, i.e. a sclerometer and ultrasound, and then a comparison of the results was performed. After analyzing the results of comparative studies, it was concluded that non-destructive methods can be applied to evaluate the mechanical properties of pervious concrete, regardless of the higher proportion of pores in these concretes.
