Abstract:
While pervious concrete has received much attention as a pavement material, it has been also used in the past to construct walls like the ones at Rosehill Cemetery, in Chicago, IL. Over the past 18 years, the author made periodic observations of the condition of these walls. Although increasing incidences of visible distress have been noted, predominantly above the interface of the pervious concrete wall and the mortar-coated porous concrete foundation, the walls have performed well. The article provides a discussion on condition of the walls by examining the potential corrosion mechanisms for steel embedded in pervious concrete.
