During the hot months of the Burj Khalifa’s construction, concrete was poured mainly at night, and some of the mix water was replaced with flaked ice to lower the concrete’s temperature. A carefully designed high-performance concrete and pumping system made it possible to raise concrete more than 600 meters. Emaar says 330,000 cubic meters of concrete were used in the tower overall; that is the total volume, not the amount all pumped to record height. The Burj Khalifa was officially inaugurated on 4 January 2010.
