Corrosion of Steel Reinforcement in Concrete: Detecting, Mapping, and Monitoring

February 08, 2023

<div><a href="/blog/corrosion-of-concrete"><img loading="lazy" src="/Content/Images/uploaded/blog/2023/february/concrete-corossion-hero.jpg" alt="Corrosion of Steel Reinforcement in Concrete" style="display: block; margin-left: auto; margin-right: auto; width: 100%; max-width: 715px;" /> </a></div><p>The corrosion of reinforcing steel is a significant and preventable problem that shortens the useful lifespan of concrete structures. The mechanisms for its development and how it eventually damages the concrete structures it was designed to protect have been well-known for over 100 years. Similar to progressive disease, early detection and monitoring are the most effective strategies to minimize problems. Fortunately, innovative nondestructive instruments are making it easier and more efficient to find, follow, and repair corrosion before extensive damage occurs.</p>

Rebar in Concrete: Nondestructive Characterization of Reinforcing Steel

February 01, 2021

<div><a href="/blog/finding-rebar-in-concrete"><img loading="lazy" src="/Content/Images/uploaded/blog/2021/February/detecting-rebar-in-concrete.jpg" alt="Rebar in Concrete: Nondestructive Characterization of Reinforcing Steel" style="display: block; margin-left: auto; margin-right: auto; width: 100%; max-width: 715px;" /> </a></div><p>Advances in technology continue to refine concrete cover meters and rebar locators, which have been around for decades and used to locate and identify concrete reinforcing steel accurately. They are integral to nondestructive evaluations of reinforced concrete structures and pavements to prevent damage to the reinforcing steel within the structure when drilling or cutting reinforced concrete. This blog post explores the features and capabilities of some of these popular instruments.</p>
