Burlington Bridge Abutment (2006)
CeramycShield was applied to a cleaned area of the Burlington Bridge abutment, Burlington, NJ in 2006. This project was designed to show the photocatalytic and oxidative self-cleaning effects of the CeramycShieldTM technology. New Jersey is noted for high summer humidity and algae growth on concrete assets. One can see from the images that the algae have failed to return to the surface, and the surface remains pristine.
Most types of biological growth emit acids that etch the surface and erode concrete in effect creating more habitat. CeramycShieldTM has a very strong photocatalytic effect (absorbs UV energy to create free radical hydroxide ions from humidity), and is biologically impervious to algae, fungi, bacteria, and other microbial life due to the metallic elements in the alumina-zirconia silicate inorganic polymer. CeramycShieldTM also stabilizes the surface chemistry of concrete, stopping carbonation and environmental exposure-driven erosion, allowing concrete to remain pristine.
