A research team at the Indian Institute of Technology Bombay has developed a new surface probe to measure the extent of corrosion in concrete rebar, which they say is more sensitive and accurate than conventional measurement techniques.
In the final column of this three-part series, longtime AMPP member Byron Evetts provides his perspective on the Champlain Towers South recovery efforts and wreckage in the days after the devastating collapse.
Tanya Brown-Giammanco, director of disaster and failure studies, explains NIST’s role in investigating structural disasters and why these probes can take years to complete.
Artisans at the Letterkenny Army Depot are now using cold spray technology to perform non-structural repairs, including repairs of corrosion and other surface defects. Cold spray offers additional repair benefits because of a lower operating temperature.
Charles S. Brown, PCS—deputy director of coatings at engineering, design, planning, and construction management firm Greenman-Pedersen, Inc.—offers a detailed checklist of safety and personal protective equipment (PPE) considerations when at a jobsite.
Viscoelastic coatings are able to instantly bond to surfaces without the need for much surface preparation, nor do they require preheating or curing time. Solutions can be tailored to specific problems by adding additional layers that provide extra protection, depending upon the need.
In part two of this three-part series, longtime AMPP member Byron Evetts provides his perspective on the Champlain Towers South recovery efforts and wreckage in the days after the devastating collapse.
There is growing concern that prestressing steel strands within post-tensioned tendons could experience hydrogen embrittlement. One proposed source of hydrogen is galvanic coupling that may exist between the galvanized steel duct and the steel strands.
Carbon fiber strands have a tensile strength comparable to steel, but they resist corrosion and require less maintenance over time. Longer service life is the major benefit, according to Michigan Department of Transportation officials.
More formalized than existing groups with moderators and formed under AMPP program committees, professionals can engage with those who share a common interest, demographic, or are from the same geographic area.
Stainless steels differ in terms of corrosion resistance, and the need to determine their corrosion resistance is essential. A standard test method that is reliable, reproducible, and quick is crucial.
The first-ever AMPP Annual Conference + Expo took place during March 2022 in San Antonio, Texas. Here’s a look back at some of the key takeaways for corrosion control and protective coatings professionals.
In the debut of this three-part series, longtime AMPP member Byron Evetts provides his perspective on the Champlain Towers South recovery efforts and wreckage in the days after the devastating collapse.
The Pacific Northwest National Laboratory is currently conducting validation research on cold spray technology, which represents the newest addition to PNNL’s suite of solid phase processing (SPP) tools.
Data presented in this article show that an AC/DC approach offers superior corrosion inhibition performance when compared to incumbent closed loop corrosion inhibitors based on molybdate and filming amines.
