The client was developing the Mohammed Bin Rashid al-Maktoum Academic Medical City in Dubai Healthcare. This development includes the construction of the University Hospital built over an area of 130,000 m2 (1,399,308 ft2).
Construction started in 2007 but as the economic crisis struck Dubai, construction was put on hold.
Recognizing the corrosive environment of the UAE where salt-laden air is combined with high levels of humidity and temperature, the client sought a method of preserving the exposed steel reinforcement while construction work was suspended.
The solution was recognized in Cortec’s MCI® CorShield® which is a waterborne preservative that provides protection to metals in unsheltered environments.
MCI® CorShield® was tested in accordance with ASTM A944-99 at American Engineering Testing, Inc. which concluded that “MCI® CorShield® bond strength of the reinforcing steel bars to the concrete was equal or better than the control.” This allowed it not to have to be removed prior to future concrete embedment.
The exposed steel was treated with an application of MCI® CorShield® in June 2009.
The site was inspected two years after treatment and the steel was found to be in the same original condition.
