Kingdom Tower could rely on Burj for answers

Concrete technology could share Burj Khalifa DNA to hit new heights

The Burj Khalifa is providing a blueprint for potential Kingdom Tower suppliers.
The Burj Khalifa is providing a blueprint for potential Kingdom Tower suppliers.

The developers of the concrete technology used on the Burj Khalifa believe that local raw materials in Saudi Arabia will be a determining factor in how the Kingdom Tower is built.

Cameron Bellman of BASF, the company that developed the admixture, Glenium SKY, for Burj Khalifa explained that his company would not need major breakthroughs to cope with the heat encountered during the Saudi summer, or the height of the 1km Kingdom Tower.

“The DNA would be the same and the concrete technology exists to deliver the high strength needed. Certainly a Putzmeister or Schwing could cope with the pumping,” he says. “But much will depend upon the raw materials locally available to the ready-mix producer.”

If the plans demand going beyond the limitations of the ready-mix and pumps, he points out that the Burj Khalifa could again provide answers.

“I know Samsung considered using a platform at 400m for secondary pumping. But due to the mix rheology this was not required and the concrete was pumped the 606m through one line at the base of the tower.”
