NEWS ALERT: Oil-Eating Microbes Help Clean Auto Repair Shop Floors

Auto repair shops are notorious for having dirty, greasy floors stained by frequent automotive fluid leaks and spills. Cleaning these petroleum-based stains is often a difficult to impossible job that sometimes requires blasting for enough stain removal power. Cortec® offers a simpler solution that relies on “green” chemistry to chase after the oily residues on the garage floor, at gas stations, or in parking lots.

auto repair shop- MCI-2061

Cortec® MCI®-2061 is a biological-based cleaner/degreaser formulated for cleaning concrete, asphalt, and other hard surfaces. It combines powerful cleaning chemistry with microorganisms capable of biodegrading hydrocarbons that stain concrete and other hard surfaces. In simple terms, biodegradable surfactants (specially suited to hydrocarbon cleaning) loosen and disperse hydrocarbons, making them more available to microbes that eat them. The main benefits are as follows:

1. The microbes of MCI®-2061 populate the substrate and provide residual deep cleaning action as they chase the oil stain through the pores.
2. MCI
®-2061 biochemistry is friendly to floors and does not corrode or destroy them.

Application of MCI®-2061 is easy. After diluting MCI®-2061 in water at a 1:10 ratio (for heavily soiled surfaces), users simply spray or pour the bio-detergent onto the soiled surface and work it into the concrete pores using a broom. The solution should be left for up to an hour (or overnight if necessary) before rinsing it away, allowing time for the microbial spores to germinate and start digesting the oil to supplement the initial cleaning action. Microorganisms that remain behind after the water rinse continue digesting hydrocarbon residuals on the driveway or shop floor. Furthermore, microorganisms that are rinsed downstream into drain lines, sewer systems, or grease traps can help accelerate biodegradation of the waste.

Thanks to MCI®-2061, cleaning oil stains off the repair shop floor or driveway no longer has to be a difficult task that is put off indefinitely. A weekly, monthly, or even quarterly cleaning with MCI®-2061 can take care of unsightly stains and improve the overall auto shop atmosphere without requiring harsh chemicals or solvents. Contact us to learn more about our biological concrete cleaners!

NEWS ALERT: How to Clean up Concrete Residue with MCI® Super Remover!

Cleanup can be a tough part of any concrete job. Even though the most stressful part of concrete placement is over, one of the next difficult tasks at hand is figuring out how to remove concrete residue that has dried or hardened on equipment and structures. MCI® Super Remover offers a powerful solution to this sometimes seemingly impossible chore.

MCI® Super Remover offers a powerful solution to this sometimes seemingly impossible chore.

Why Remove Hardened Concrete?

Cleanup is an important part of equipment maintenance. Hardened concrete not only affects the appearance of ready-mix trucks and structures; it can also hinder the ability of equipment to work. However, using the wrong removal product may damage equipment, take too long, or be excessively dangerous to users. Sometimes, workers resort to hammers and other tools to try to chip off the concrete.

The Ease of MCI® Super Remover

MCI® Super Remover offers a powerful solution that is easy to use and works quickly. It can remove both calcium carbonates and oxides, making it applicable for concrete residue, scale, and rust. Although proper handling and PPE (personal protective equipment) should still be used, MCI® Super Remover offers a safer alternative to hydrochloric acid. MCI® Super Remover should be applied undiluted to the affected surface for 30 minutes to three hours, depending on the thickness and age of the residue, then scraped and/or pressure-washed to remove the softened residue. A final rinse with an alkaline cleaner such as VpCI®-414 can be used to neutralize the surface and provide flash rust protection. MCI® Super Remover can also be collected after use, filtered, and reused if its pH remains within its specified range.

Make MCI® Super Remover Part of Your Cleanup Routine

Whether you are having trouble with concrete cleanup on drum mixers, ready-mix trucks, construction equipment, or batching plant structures, MCI® Super Remover is a practical way to help keep components looking as good as possible after a one-time job or as part of a regular maintenance routine. Contact Cortec® to learn more about this super concrete removal option!

NEWS ALERT: New Five-Pound MCI® Grenade™ Makes Concrete Admixture Dosing Easier!

November 2, 2023

Dosing corrosion inhibiting admixtures into the ready-mix truck has simply gotten easier with the creation of MCI® Grenades in 5-pound (2.3
kg) bags! Rather than having to add 10 regular MCI® Grenades to the concrete truck, ready-mixers only need to add two 5-pound MCI® Grenades
to ensure the batch has enough Migrating Corrosion Inhibitors to protect embedded reinforcement. That means just one 5-pound MCI® Grenade is needed per half truck!

New Five-Pound MCI® Grenade™

MCI® Grenades are water-soluble pouches that contain pre-measured MCI®-2006 NS powder, a Migrating Corrosion Inhibitor™ admixture for reinforced concrete. The bag and corrosion inhibitors easily dissolve in contact with concrete mix-water and disperse throughout the batch during mixing. Once inside the structure, this blend of amine carboxylates forms a protective molecular layer on embedded reinforcing steel, helping enhance the durability and service life of concrete structures.

Not only can MCI® Grenades be specified in new construction and repair projects, but they are also a great backup plan to have when dosing liquid admixtures such as MCI®-2005 NS. In a worst-case scenario where MCI® dosing equipment becomes clogged with foreign materials midpour, or a shortage of MCI®-2005 NS is discovered too late, contractors will be relieved to have MCI® Grenades on hand to continue an already stressful job without unnecessary delays.

MCI® Grenades are now available in four handy sizes to match the size of the repair or construction job. Dosage is as follows:

  • One MCI® Mini Grenade per 0.5-0.6 ft³ (0.015 m³) of concrete
  • One 1.1 lb (500 g) MCI® Grenade™ per 1 yd³ of concrete
  • One Metric MCI® Grenade™ per 1 m³ of concrete
  • One 5 lb (2.3 kg) MCI® Grenade™ per 5 yd³ (3.8 m³) of concrete

Contact Cortec® today to order your supply of MCI® Grenades based on job size!

NEWS ALERT: A Little Preventative Maintenance Goes a Long Way: Mining and Ready-Mix Trucks

Heavy equipment is essential to the mining and construction industries. However, work crews face two major upkeep challenges: (1) Harsh environments lead to corrosion and shortened service life and (2) Spilled cement and asphalt are difficult to remove once hardened. Cortec® is seeking to help crews minimize these problems with three handy preventative maintenance coatings.

MCI® Creteskin®

Option 1: Annual Preventative Maintenance

VpCI®-391 is a water-based coating that can be sprayed directly over bare or painted metal. It leaves behind an inconspicuous non-tacky coating that inhibits corrosion and thus extends the service life of the equipment. Since VpCI®-391 is technically a removable coating that can wear off over time, it should typically be reapplied once a year during annual preventative maintenance activities. Heavy equipment owners/users who have applied VpCI®-391 in this way have seen a significant improvement in service life in harsh conditions.

Option 2: Long-Term Preventative Maintenance

For workers who want to get more time out of their “paint job,” EcoShield® VpCI®-386 serves as an outstanding permanent water-based corrosion inhibitor coating. It can be applied as a very thin clear coat over bare metal and painted surfaces, or, if desired, tinted to match the truck’s color theme. It can slow down the corrosion process for multiple years without reapplication.

Option 3: Corrosion Protection + Easier Cleaning

MCI® Creteskin® is a great option for ready-mix or asphalt trucks that are incredibly difficult to clean after concrete or asphalt residues dry on the surface. Spraying a coating of MCI® Creteskin® on the equipment before it is used leaves behind a coating that cures to a slightly waxy finish and prevents adhesion of cementitious materials. This makes it easier to clean hardened materials with high pressure water instead of abrasive blasting or acid removal. It also inhibits corrosion. Touchup can be done as needed to areas of the coating that wear away after normal use. Although it takes more initial thought and effort to apply a protective coating before the problem happens, doing so pays off in the long run by helping equipment last longer and making it easier to maintain. Take some time today to consider what situations your equipment will be up against and contact Cortec® for help picking the best coating for your application.

News Alert: Idaho Adds Another MCI® Admixture to its QPL! MCI®-2005 NS

Cortec® is pleased to announce that the Idaho Transportation Department (ITD) has added another MCI® admixture to its Qualified Products List (QPL)! MCI®-2005 NS was approved for the ITD QPL on July 13th. It falls under category “709 Concrete Curing Materials and Admixtures,” subcategory “Type S – Corrosion Inhibitor for Concrete.”

MCI admixtures

While lack of DOT approval in a certain state does not mean that product cannot be used, department of transportation (DOT) approval is important for three reasons:

  1. It allows engineers to easily specify MCI® in DOT construction projects for these states/provinces.
  2. It lends credibility to engineers desiring to use MCI® Technologies in non-DOT projects.
  3. It ultimately can improve the quality of construction by qualifying good-performing products through review according to industry standards.

MCI®-2005 NS is a concrete admixture that delays time to corrosion and reduces corrosion rates once started. Unlike calcium nitrite (CNI) admixtures, which accelerate set time and can cause workability problems, MCI®-2005 NS does not affect set time and has received outstanding feedback from contractors all too familiar with the early set problems of CNI in hot weather. It is an excellent addition to the three MCI® products already approved in Idaho, a state where concrete corrosion inhibitors are strongly needed to combat deicing salt corrosion! Contact Cortec® to learn more about our MCI® DOT approvals.

Corrosion Protection on Pelješac

Spanning a stretch of the Adriatic Sea, the Pelješac Bridge connects two parts of Croatia previously separated by water on one side and a neighboring country on the other. Due to design demands for a 130-year service life in the presence of a harsh saltwater environment, engineers of the Pelješac Bridge specified a multi faceted rust prevention strategy. In addition to AC coatings, cathodic protection, thick concrete cover, and stainless steel reinforcement, MCI®-2018 was applied to the bridge’s substructure piers for dual water repellency and corrosion inhibition to prolong service life.

Benefits of MCI®-2018

MCI®-2018 is a 100% silane water repellent containing Migrating Corrosion Inhibitors. As a surface applied corrosion inhibitor that does not change the appearance of the structure and is certified to meet ANSI/NSF Standard 61 for drinking water system components, MCI®– 2018 aligned well with the project’s aesthetic and environmental goals. Its CE certification under EN 1504-2 (2+ system) for superficial protection of concrete also qualified it for use in Europe.

As a company founded by Croatian-American entrepreneur Boris Miksic, Cortec® is proud to be part of this award-winning engineering and geographically strategic achievement in Croatia. Learn more about Cortec’s role in the Pelješac Bridge here!

NEWS ALERT: Comparing Options for Rusted Rebars in Concrete Patch Repairs

VpCI Corrverter on Rebar

Concrete spalling happens when corrosion on embedded rebar expands so much that it causes the concrete cover to break and fall off. The only responsible response is to repair the gap and seek to slow down the corrosion process. But what are the best materials to use on the exposed rusted rebars? Here is a look at two popular options.

  • 3K Bonding Agent

One commonly used product is a 3K material containing epoxy, corrosion inhibitor, and a bonding agent. These components are mixed and applied to clean metal reinforcement before the application of repair mortar. The coating works as a “glue” to bond the rebar or old concrete to the new patch material while also inhibiting corrosion on embedded reinforcement.

  • CorrVerter® MCI®

CorrVerter® MCI® Rust Primer is a single component water-based primer that converts rusted surfaces to a passive layer using a combination of chelating agents and a high solids waterborne latex with extremely low water vapor permeability. It can be applied to rusty rebar and patched with a concrete repair mortar once the primer has dried.

Some of the key differences between the two products are summarized in the following table:

3K Bonding Agent CorrVerter® MCI®
Surface Prep
Clean, rust-free surface is required; this typically means sandblasting

Sandblasting is labor-intensive and cannot clean the back of the rebar

Sandblasting byproducts create an environmental concern and must be disposed of carefully

Application to corroded surface is okay if loose rust has been brushed away

Repair mortar can be applied directly over CorrVerter® MCI®—no bonding agents required

Treatment of the back of the rebar is feasible with brush application

Application and Disposal
Three components must be mixed together and used within 1-2 hours or discarded

Two coats needed, 2-3 hours apart

Workers have 8-16 hours in which they can apply repair mortar for maximum bonding effect

One component; only needs enough mixing to ensure solids are evenly distributed

One or two coats needed; second coat can be applied after 20-30 minutes

Unused material can be covered and used later

Workers should wait 12-24 hours before applying patch material; minimal impact on bond strength thereafter

While both repair methods are valid, CorrVerter® MCI® offers obvious advantages in terms of reducing waste and simplifying labor. Which do you prefer? Contact Cortec® to learn more about the CorrVerter® MCI® advantage for spalling repairs!
