Abstract
Portland cement Pervious Concrete (PCPC) is a special type of concrete characterized by a highly connected pore system that allows water from different sources to infiltrate through to recharge the ground water. This paper present selected results on the key mechanical and hydrological performances of pervious concrete designed with different recycled aggregates from various sources and materials types. Seven pervious concrete mixes containing different recycled materials in addition to a control mix, were optimized and tested in terms their mechanical and hydrological properties. The results obtained indicate acceptable mechanical properties of the designed PCPC with an appropriate water penetrability depending on the granular system and compaction effort employed. Among these optimized mixes, selected mixes meeting strength and permeability requirement for a PCPC could be used in some common flat applications as an efficient drainage system. Potential use of these pervious concrete optimized mixes based on recycled materials includes but not limited to sidewalk, pavement in low traffic area, parking lots in regions known by heavy rainfall, floor for car washing stations, etc.
