Abstract

Pervious concrete is a unique and effective material used to tackle important environmental problems, to maintain green, sustainable growth, and to reduce storm water runoff and pollutants. Clogging of pervious concrete is an important potential issue in serviceability, considered one of the primary limitations of pervious concrete systems. The sediment deposition pattern of pervious concrete was determined using three clogging materials: clay, sand, and clayey silty sand. The clogged specimens were cleaned by pressure washing, vacuuming, and a combined method. In total, ten clogging and cleaning cycles were carried out on each sample to evaluate the draining capacity of the pervious concrete. The clogging test was assessed by measuring the infiltration rate during clogging and after cleaning, for each cycle. The experiment results showed that a reduction in permeability due to different types of sedimentation material as well as recovery in permeability was achieved after applying various cleaning methods.

Abstract

In recent years, the application of pervious concrete (PC) in urban areas has expanded mainly due to its high potential for controlling and guiding surface waters and floods. However, its poor mechanical properties compared to conventional concrete hinder its widespread application and limit it to parking lots, sidewalks, and local streets. Therefore, identifying the parameters effective on PC’s physical and mechanical properties and durability could help resolve its weaknesses and enhance its performance. This review article investigated and discussed the PC’s performance properties and weaknesses and explore the solutions available for improving these properties. Based on a review of the literature, the solutions included the PC’s mix design basic property variations and the incorporation of various additives. The common mixture utilized in most studies contained a water-to-cement ratio of 0.25:0.35, resulting in compressive strength of 7–27 MPa, porosity of 15–35%, and permeability of 0.2–1.22 mm/s.
