Corrosion Topics Discussed this
Month at materialsperformance.com
• Impressed Current Anode Systems for Jetty Piling
Protection—One of the areas where cathodic
protection (CP) is commonly applied to marine
structures is the steel piling systems on jetties
and piers. This article discusses the design and
implementation of CP on a newly constructed
jetty in Surabaya, Indonesia.
• Key Indicators Can Reveal Signs of Concrete
Parking Structure Corrosion—Experienced con-
crete maintenance and restoration specialists
explain the unique challenges in protecting
parking structures from a constant onslaught
of environmental stressors and wear and tear,
along with examples of successful repair
techniques.
• Battling Building Envelope Corrosion—
Efficiently managing the effects of concrete
corrosion can extend the life of a building;
however, concrete is not the only component
threatened by corrosion. On any building, both
the cladding and fasteners holding it in place
are exposed to varying degrees of corrosion.
• Teaching Cathodic Protection with an Outdoor
Pipeline Integrity Lab—A major U.S. university
is using funding to develop a new outdoor
pipeline integrity lab, which will include buried
pipe with an active rectifier to simulate real-
life activities.
• Test Protocol Evaluates Concrete Repair with
Sacrificial Anodes—One of the most common
drivers of concrete repairs is corrosion of the
concrete's steel reinforcement, often caused by
chloride ions in the environment entering the
concrete and eventually reaching the embed-
ded steel.
• Polyurea Coatings Protect Aging Concrete
Wastewater Infrastructure—Advanced polyurea
coatings and liners provide strong, flexible
waterproofing to bridge cracks and protect
against future cracking and deterioration.
• Cathodic Protection Retrofit on an Aging
Pipeline—As pipelines age, it is important to
verify the effectiveness of the coating and
cathodic protection systems that protect them
against external corrosion, and implement
remedial actions if necessary.
