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.”

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.
