Corrosive Concrete Halts Construction Of Second Tallest Building In The World.

Ping'an International Finance Center
Ping'an International Finance CenterIt’s probably too late to reconsider constructing the 660m, 116-story Ping’an International Finance Center so hopefully they can get it right. What’s halting construction? It turns out that several contractors supplying concrete to the project may have been using unprocessed sea sand in their mix which over time, could compromise the stability of the future 2nd tallest building in the world and the tallest building in China. From Dezeen:

“While cheap sea sand offers cost-saving opportunities for contractors, the salt and chloride present in it can corrode steel reinforcements over time and ultimately cause a building to collapse.”

With the delays and the possible added cost of removing and replacing all of the skunk-concrete, maybe the developers will stop at 58 stories and cut their losses. The Ping’an International Finance Center was only going to be the second tallest skyscraper in the world anyways. [Dezeen via Inhabitat]
