For instance, the world’s tallest building, the Burj Khalifa in Dubai (829m high) used 45,000 cubic metres of concrete to construct 192 piles, each buried 50m into the ground. A cathodic protection system was also installed under the mat, to minimize any detrimental effects of corrosive chemicals, which may be present in local ground water. Khalifa is designed as an all + 585.7m reinforced concrete building with high performance concrete from the foundation level to level 156, and is topped with a structural steel braced frame from level 156 to the highest point of the tower. From an initial concept through completion, a combination of several important technological innovations and innovative structural design methods have resulted in a superstructure that is both efficient and robust. The piles were made high density, low permeability C60 grade SCC concrete placed by tremie method utilizing polymer slurry. 5 The piled-raft foundation of Burj Khalifa Over 45,000 m3 (58,900 cu yd) of concrete, weighing more than 110,000 tonnes were used to construct the concrete and steel foundation, which features 192 piles buried more than 50 m (164 ft) deep.
