New developments in low corrosion economical construction products
New developments by MMFX Steel Corporation of America in Steel Microstructures resulting from research and development at the Nano Level have created exciting new materials that stand ready to change the way in which reinforced concrete structures of the future are designed and survive the corrosive environments that have previously limited the service life of all structures subjected to high chloride attack. It is estimated that the costs to repair damaged infrastructure buildings, parking structures and bridges in the United States is in the order of dollar 100 Billion and the hidden nature of the problem is raising great concerns for safety of the users and creating a feeling that a National Emergency is rapidly developing. Thousands of bridges in the United States alone require extensive rehabilitation or replacement because of corrosion of the reinforcing bars in the concrete structures, particularly where heavy salting is necessary because of icing conditions. This new technology has resulted in steel Microstructures that have produced highly corrosion resistant materials by altering the materials at the atomic level without significantly increasing the production costs of the steels nor requiring the use of epoxy coatings. But assuring that these Nanostructures are present, however, requires the use and analysis by Transmission Electron Microscopy (TEM) to verify. Since this capability is not normally found in commercial material testing laboratories, this new technological advancement in material science, must depend on developing the resources in electron microscopy to a point of common practicality. Currently, these facilities and instruments are available mostly in private laboratories or in Universities making it necessary to limit their use and making it necessary to develop other means to certify these materials. This paper is a Work-In-Progress Report of this activity on the new MMFX Steels and the process being developed to respond to these challenges.
