The first children’s hospital in Dubai was built with a footprint of 55,000 m² (592,015 ft²). An aggressive environment with high salinity, high humidity levels, high temperatures, and a high water table posed considerable challenges for designing the structure to meet concrete durability and minimum service life requirements. MCI®-2005 was added to the concrete mix to enhance durability and maximize service life. This biobased concrete admixture (contains 67% USDA certified biobased content) inhibits corrosion by forming a protective molecular layer on the surface of metal reinforcement. It met all specifications required by the design engineering firm and was therefore accepted for use in this challenging environment.
