SILANE TREATMENTS FIGHT BRIDGE COORROSION

Silane treatment is providing to be a successful and cost-effective way of preventing the dangerous and expensive bridge deck deterioration cuased by concrete corrosion. The silane compound prvents this by penetrating the concrete, and producing a chemical reaction with it, rather than just coating the concrete. This forms a protective layer, which renders the concrete salt resistant to a point well below steel corrosion tolerance levels. Core samples taken from treated bridge decks in Oklahoma have shown that the treatment is effective in preventing corrosion, for both old and new bridges. The tests showed that the silane compound penetrated bridge decks from one-forth to one-half of an inch. This significant penetration protects the concrete for years, even on well-traveled roads and in wheelpath areas. The treated layer continues to work until it is physically worn away. (Author)
