NEWS ALERT: Cortec® MCI® Explores Weather, Concrete, and More at ICRI Spring Convention!

What are the effects of weather on concrete and construction? This was the main topic under consideration at the 2022 ICRI Spring Convention, April 4th-6th in Baltimore, MD, along with many other issues related to concrete repair. We were grateful to have a solid trio of MCI® experts (Kevin Quan, Jon Connealy, and Lisa Marston) there to represent Cortec® MCI® at our tabletop booth and in various committee meetings and educational presentations throughout the three-day gathering of construction professionals.

Networking at ICRI

The convention was marked by strong attendance, allowing our team to network with a variety of engineers, contractors, and distributors—especially from the U.S. East Coast region. The steel wool bottle demo captured a lot of interest because of the clear contrast between unprotected versus protected steel wool in water. It was great to see suppliers interested in learning more about MCI®, as well, since they stand to benefit from incorporating the technology into some of their own projects.

Educational Opportunities

Our team also had time to attend educational presentations and committee meetings, learning about everything from competitor technologies to how climate change could affect concrete durability. Lisa Marston, our Regional Technical Service Engineer with a focus on MCI®, was able to add to her skills and understanding of the field by participating in the 160 Life Cycle and Sustainability committee meeting and attending the 510 Corrosion committee and the Women in ICRI committee meetings.

Ongoing Initiatives

One topic that kept resurfacing during conference discussions was the issue of service life modeling for existing structures at the repair stage. Currently, no tools for estimating service life exist beyond what is available for new structures. This will likely be a continuing topic of discussion at ICRI as more ideas unfold on how to address this important need. Other exciting initiatives include the recent development of new task groups by Women in ICRI to encourage more involvement and outreach at the local chapter level for emergency response support, philanthropic/volunteer opportunities, education, and more.

All in all, ICRI was a great time to deepen our connections, share our specialty areas of expertise, and keep our eye on trends that will be important to all of us in the concrete and construction industries!

NEWS ALERT: Face to Face at World of Concrete 2022

The World of Concrete (WOC) was a great opportunity for many of us to not only escape the snow and cold of our home environments, but also to see the whole MCI® team and some of our distributors and reps face to face once again! The excitement of being back in person January 18th– 21st in Las Vegas was visible among the audience, which, although smaller than pre-COVID shows, was noticeably larger than the June 2021 WOC when construction season was in full swing.

As usual, the MCI® Lunch & Learn was packed with discussion about MCI® business strategies, challenges, market changes, and industry reception, as well as product updates and relevant case histories. Business aside, our reps and distributors had time to relax and attend “WOW – The Vegas Spectacular,” to be entertained by acrobats in a theatrical setting.

WOC also brought opportunities to talk with current and potential customers—some of whom seemed genuinely interested in learning about MCI® Technology for the first time. Another potential benefit of the conference was connecting with material suppliers who may be helpful resources for future R&D efforts.

Although we missed the presence of our international distributors this year, it was great to see those of you who were able to attend from Alpine Summit Enterprises , JN Lucas & Associates, M2, and SMART. We were happy to be together once again, and we look forward to seeing even more of you next year at WOC 2023!

MCI®-309: A Corrosion Inhibitor for PT Bridges and Beyond!

The history of MCI®-309 for the last 20 years has been the history of convenient and versatile corrosion protection around the globe. Since 2001, MCI®-309 corrosion inhibitor has been applied in at least 23 of the United States (plus D.C.), two provinces, and 10 countries. It has been used from Murmansk to Dubai and from Montreal to Oahu. While its most common purpose is as a corrosion inhibitor in post-tension (PT) bridges awaiting grouting, MCI®-309 has also been used to protect floating bridges and flex-float internal cavities. Just a few key projects are mentioned below.



Project Name Location Year
Round Butte Reservoir Madras, Oregon (USA) 2009-Present
St. Croix River Crossing Oak Park Heights, MN/Houlton, WI (USA) 2014-2017
Samuel De Champlain Bridge/ Réseau Express Métropolitain (REM) Light Rail System Montreal, Quebec (Canada) 2016-2019
Frederick Douglass Memorial Bridge Project Washington, DC (USA) 2020
Dubai Metro 2020 Route Dubai (UAE) 2019

Keywords: corrosion inhibitor, PT bridges, post tension cable corrosion, grouting delays, Cortec, MCI, Frederick Douglass Memorial Bridge, Samuel De Champlain Bridge, St. Croix River Crossing

MCI®-309 is a welcome answer for construction crews that face PT grouting delays due to cold weather or other interruptions after PT placement. In the U.S., state and federal requirements typically call for corrosion inhibitor application if the waiting period is two weeks or longer. MCI®-309 is a convenient choice because it is easy to apply by fogging through the PT ducts and then capping the ends. Little or no surface prep is required, and the corrosion inhibitor does not need to be flushed out prior to grouting because it does not affect bond strength. These factors reduce labor and minimize further exposure to corrosive elements, all while mitigating PT cable corrosion. Contact us for more info on how and where MCI®-309 has been

NEWS ALERT: MCI® PTC® Emitters – Go Beyond Reinforced Concrete Protection!

Did you know that the benefits of MCI® Technology extend beyond reinforced concrete? While Migrating Corrosion Inhibitors are most commonly used to mitigate the corrosion of embedded rebar in new or existing concrete, they offer much broader benefits, as demonstrated by PTC Emitters.

How PTC Emitters Work
PTC Emitters are breathable pouches that contain Migrating Corrosion Inhibitor™ powder. They can be placed in any void space enclosure where corrosion protection is needed. The MCIs vaporize through the pores of the pouch, diffuse throughout the space, and finally form a protective molecular layer on surrounding metal surfaces. Distribution of the MCI® vapors in large spaces can be enhanced by blowing dry air through the pouches, if needed.

Designed to Protect Suspension Cables
PTC Emitters were initially designed to mitigate corrosion on suspension bridge cables. These cables are made of many metal strands twisted together
with voids that can capture moisture and foster corrosion between the strands. Dehumidification systems are sometimes used to force dry air through these cables in an effort to reduce moisture and stave off corrosion. PTC Emitters are a perfect backup to the deficiencies of dehumidification. They can be easily placed in chambers added to the dehumidification piping for the purpose of blowing Migrating Corrosion Inhibitors throughout the intricacies of the suspension cable strands.

One Technology, Many Uses
PTC Emitters can also be adapted to many other construction/structural applications where metal needs corrosion protection inside a void space:

  • Tubular structures, pipes, and vessels
  • Segmental concrete bridge tendons/cables
  • Reinforcement inside box girder segments

If you work in construction or structural maintenance, be sure to contact us for more information and ideas on how PTC Emitters can provide the corrosion protection needed in your various applications. Learn more:

We are excited to announce competitive new pricing for MCI® Grenades! The cost-reduction comes thanks to the automation of our MCI® Grenade™ packaging system, which lowers production costs by allowing greater economies of scale. This translates into cost savings for customers who will be able to get more for their money next time they order MCI® Grenades. Customers will enjoy more savings per MCI® Grenade while also getting them in larger quantities: 40 MCI® Grenades (32 Metric MCI® Grenades) per drum instead of only 20 MCI® Grenades per carton. This is a great opportunity to stock up for emergencies on an economical, easy-to-use form of concrete corrosion protection and encourage more widespread use among ready-mix suppliers, contractors, and engineers.

MCI® Grenades have long been a convenient, cost-effective method of adding Migrating Corrosion Inhibitor™ admixtures to construction projects. Whether for a concrete repair or simply as a backup admixture for a new concrete pour, the MCI® Grenade™ is a great way to toss a powerful dose of corrosion protection into the ready-mix, while getting all the advantages of a nitrite-free admixture. The water-soluble packaging dissolves in contact with the mix water, releasing Migrating Corrosion Inhibitors to be dispersed throughout the batch. MCI® Grenades can be incorporated at the ready-mix plant or added directly to ready-mix trucks and portable mixers at the jobsite. One MCI® Grenade™ provides enough corrosion protection for 1 cubic yard of concrete (one Metric MCI® Grenade™ protects 1 m³) and migrates to adjacent areas to protect surrounding metals and minimize the ring anode effect.

NEWS ALERT: Cortec® Excited to be Part of Host Chapter for ICRI Fall 2021 Convention

November 2, 2021

Cortec® was excited to return to a live convention for ICRI’s Fall 2021 convention in Minneapolis, MN! Our entire MCI® team – Ashraf Hasania (MCI® Technical Sales & Product Manager), Kevin Quan (MCI® Regional Sales Manager, East Coast), Jon Connealy (MCI® Regional Sales Manager, Midwest), Lisa Marston (MCI® Regional Technical Service Engineer) and Jessi Meyer (Vice President – Technical Sales & Product Management) – was on hand to welcome attendees to the convention and educate them on
the MCI
® product line at our tabletop booth. As a part of the Minnesota Chapter of ICRI, Jessi Meyer helped with the chapter hosted events of Axe Throwing at Flannel Jax’s in St. Paul, and a Riverboat Cruise down the Mississippi River. First time attendees, Kevin Quan and Lisa Marston were able to participate in a First Time Attendee’s reception on Monday evening as well as a scavenger hunt.

Attendance was a bit lower than normal as the first live convention since Fall of 2019, however all attendees seemed genuinely happy to see a return to meeting in person again! Our team continued to play an important role in ICRI committees participating in the Corrosion Committee, Membership and Marketing Committees, and the Life-Cycle and Sustainability Committee. Marston and Meyer also enjoyed attending the Women in ICRI committee and listening to guest speaker Natalie Faber, who spoke about her newly founded 501 (C) 6 program called 3C, which helped to place 155 disadvantaged youth in concrete repair industry internships in its first summer program. “It’s amazing to see what a difference one person can make, and I am excited to see how we can help the program grow in Minnesota and other areas around the country,” Meyer commented.

Cortec® looks forward to following up with the many individuals who visited the MCI® booth during the October 10th-13th convention and
anticipates seeing many familiar and unfamiliar faces once again at the 2022 ICRI Spring Convention in April 2022! Look for details on the

Equip Your Construction Crew with a Full PT Protection System!

PT (post-tensioning) cables typically consist of relatively narrow metal strands under high tension. Even a minor loss of cross-section from corrosion damage could lead to snapping and failure, resulting in serious structural damage. MCI®-309 is an extremely efficient method of dry corrosion mitigation to meet this critical need for protecting PT strands during grouting delays. Even better, Cortec® MCI® Technology goes a step farther by offering a full protection system for each stage of the PT construction process.

Shipping and Storage
PT strands are often exposed to unpredictable and corrosive environments during transport and onsite storage. Instead of simply covering them in conventional plastic, manufacturers and/or construction crews can wrap them in MCI® Construction Film for an added layer of corrosion protection. Migrating Corrosion Inhibitors in the plastic form a protective molecular layer on all accessible metal surfaces packaged within and do not need to be removed before PT placement.

PT Strand Placement
Protection of PT strands after placement in the PT duct is the most familiar PT corrosion concern. State and federal regulations often call for corrosion inhibitor application if grouting will be delayed two weeks or more. MCI®-309 is the optimal choice because it is easy to apply with little to no surface prep, typically does not need to be removed before grouting, and does not adversely impact bonding with grout. (Check out this video to see how easy it is to apply MCI®-309:

Grouting and Beyond
Mini MCI® Grenades can be added to the PT duct grout to provide ongoing protection in the completed structure. Mini MCI® Grenades contain Migrating Corrosion Inhibitors packed in water-soluble bags that easily dissolve when added to the grouting mix. One Mini MCI® Grenade® protects 0.4-0.6 ft³ (0.011-0.017 m³) of grout mixture.

By incorporating MCI® at every stage, contractors can promote a longer service life for the all-important tendons that support PT structures, thus enhancing the durability of the entire structure. Contact us for further assistance:
