Burj Khalifa

Cortec’s MCI® 2005 was incorporated in the concrete mix design for the podium structure to achieve the desired 100 year service life. The building sits on a concrete and steel podium with 192 piles descending to a depth of more than 50 meters. A total of 45,000 m3 of concrete was used in the foundations with a weight in excess of 110,000 tonnes.

Application
Cortec’s MCI® 2005 was incorporated in the concrete mix design for the podium structure. The building sits on a concrete and steel podium with 192 piles descending to a depth of more than 50 meters (164 feet). A total of 45,000 m3 of concrete was used in the foundations with a weight in excess of 110,000 tonnes (121,254 US tons).

Why MCI® was chosen

EMAAR properties engaged GHD to review the proposed design and assess the durability of the materials required to provide the 100 year design life. After a thorough review of multiple technologies, MCI® 2005 was chosen as an additional layer of protection in the substructure which is exposed to harsh groundwater conditions. The groundwater in the are contains more chloride than seawater as well as other contaminants.

Conclusion
Burj Khalifa’s construction used 330,000 m3 (431,500 yd3) of concrete, 55,000 tonnes (60,627 US tons) of steel rebar, and 22 million man- hours to complete. Burj Khalifa is expected to hold up to 35,000 people at any one time and has a 100 year design life.
