  • Introduction

    Two practical methods of treatment are available to preventsteel frame corrosion:

    (a) Treating the steel and changing the environment (e.g.,removing the facade, applying protective coatings to the steel, andpreventing moisture ingress to the facade); or

    (b) Controlling the corrosion process electrochemically (e.g.,with CP).

    The former is the current standard method of treatment; however,the widespread stripping of a facade is often impractical andprohibitively expensive because of the necessity of removing largesections of masonry to allow access to the steel frame. The removalof masonry is also of particular concern when heritage buildingsare involved. In such applications, a conservation strategy for thefacade adds considerable value.

    The principal electrochemical process for controlling corrosionis CP. CP offers many benefits over traditional repairs, includingsubstantial cost savings, minimal disruption to the buildingoccupants, and conservation benefits that are of particularimportance in heritage buildings. The CP of steel-framed buildingsis possible because the protective current can be passed throughthe stonework or masonry to the steel through the mortar/masonrycontact. However, although the steel and masonry layout detailsoften exist, it is not always easy to determine the connectionbetween the two elements.
