Preventing steel rebar from corroding in concrete, and thus destroying the concrete, is one of those problems that we must solve. We’ve all seen too many rust-damaged structures. This new admixture from Cortec promises to double the time until corrosion starts and then reduces the corrosion rate by up to five times over the life of the structure. MCI-2005 NS protects by using a migratory corrosion inhibitor (MCI) function. When incorporated into the concrete mix, the MCI seeks out and forms a corrosion-inhibiting protective layer on metals. When used with repair mortars and grouts, it will migrate a considerable distance to undisturbed concrete, providing effective corrosion protection to rebar already in place. Ideal for things like parking structures. Visit
