- THAT’S A FACT
If America’s 47,744 miles of interstate highways were paved with concrete, 10,989,557 gallons of fuel would be saved each day. - EAR TO THE GROUND
Service Life Engineering has become its own powerful field of study with immense impact on the future. - THAT’S A FACT
Concrete is a light color, which reflects from 33 to 50 per cent more light than asphalt, and can even lower the average town temperature by six degrees.
Corrosion Performance Testing in Accordance with AASHTO MP 18M/MP 18-09
Laboratory Evaluation of Corrosion Performance—MMFX 2 (ASASHTO MP18/ASTM A1035-Grade 100) concrete reinforcing bars
To evaluate the corrosion performance of MMFX 2 (AASHTO MP18/ASTM A1035-Grade 100) concrete reinforcing bars according to the requirements of AASHTO Standard Specification: MP 18M/MP 18-09—Uncoated, Corrosion-Resistant, Deformed and Plain Alloy, Billet-Steel Bars for Concrete Reinforcement and Dowels.
The scope of the work was to evaluate the corrosion performance of MMFX 2 reinforcing bars using laboratory electrochemical corrosion tests. Specific tests were polarization resistance and potentiodynamic polarization tests on No. 3 through No. 11 (10-36 mm) bars of MMFX 2, using a No. 4 (13 mm) ASTM A 615, Grade 60 bar for comparison.
In addition, micrographs of etched specimens were taken as an index for confirmation of the microstructure for each of the test bars.
The results show that MMFX 2 meets the requirements of AASHTO Standard Specification: MP 18M/MP 18-09—Uncoated, Corrosion-Resistant, Deformed and Plain Alloy, Billet-Steel Bars for Concrete Reinforcement and Dowels.

TCG did an excellent job in performing this study documenting the corrosion performance of our product to a new AASHTO Specification. This will be of great benefit to us and the industry by providing another alternative for enhanced corrosion performance of reinforced concrete, through the use of uncoated corrosion-resistant reinforcement (CRR) steel bars.
