At an incredible
828 metres (2,716.5 feet) and more than 160 storeys, Dubai’s Burj Khalifa is
the world’s tallest building.
Engineers,
designers, architects and skilled workers from more than 100 countries were
involved in the making of the building. The construction took 22 million
man-hours, where more than 12,000 dedicated personnel ensured the seamless
progress of the building.
Burj Khalifa’s
primary structure is made of reinforced concrete. The construction used
330,000 m3 of concrete and 55,000 tonnes of galvanized steel rebar. A cathodic
protection system is in place under the concrete to neutralize the groundwater
and prevent corrosion.
Due to the hot
and humid outside conditions, an additional protective coating to the structure
was required. Thus, the steel pipes used in the inner skeleton of the building
were hot-dip galvanized along with the steel construction around the
entrance to maximise protection.
The world’s
tallest building is another testimony of the strength of Zinc. We all have
Zinc in our lives.
