Steel-reinforced concrete is a strong, reliable structure that can withstand intense environmental exposure. But moisture, chlorides, carbon dioxide gas, and other aggressive agents can (over time) penetrate concrete, causing corrosion of the reinforcement bars. Rust on the rebar expands, causing pressure that cracks and weakens the concrete infrastructure.
ELGARD® mixed metal oxide (MMO) on titanium anodes is the key to using cathodic protection to prevent the corrosion of steel-reinforced concrete structures.
Since the mid-1980s, ELGARD® MMO anodes have been used to prevent corrosion and increase the life of:
buildings, bridges, stadiums, parking garages, monuments
power generation cooling towers, marine structures, dolphins
