The construction of this 828 m tall, reinforced concrete tower structure, broke several records during its construction. the first time a tower of this height is attempted, a combination of several important technological concepts and innovative structural design methods were utilized in its construction.
  • The most important building materiel of Burj Khalifa is reinforced  concrete . A special concrete was needed because of the high pressures of the building's  weight  and the hot local  climate .  Persian Gulf temperatures  that can reach  Template:Convert/c . Any major cracks could have could have caused a large amount of damage to the building. Pressure  means how much something is pushing on something else expressed as  force  per unit  area .P=F/A.   refuge floors : fire-resistant construction. This floors can accommodate ppl in the case of fire and smoke.
  • The foundation of the building is 15 metres (49 ft) deep. It was built with 192  columns  being put into the ground. Each column was 1.5m in  diameter  and 43m long. [10]  55,000  tonnes  of  steel   rebar  was used in the construction of the tower. It took 22 million man-hours to build [3] . A high  density , low  permeability  concrete was used in the foundations of Burj Khalifa. A  cathodic protection  system is used to lessen any bad effects from  corrosive   chemicals  in local ground water. Cathode Protection : Cathodic protection is a procedure used to protect an object from corrosion by making it a cathode. To make a tank a cathode, you have to attach an anode to it.  concrete with long pieces of metal called  rebar  inside to make it stronger.
