Pre-stress tested.
Chinese concrete ?
In China the responsible people would be executed. In America they are reelected to office.
Let’s be honest. China is the largest steel maker in the world, by far. There’s nothing wrong with Chinese steel overall.
There IS a problem with American planners, government officials, engineers and buyers.
Too stupid to understand the difference between cement and concrete, I see.
Maybe so. How about Chinese steel? And Chinese fasteners and related hardware all sold as being inspected, tested and certified?
Wouldn’t be the first time.
What was the name of that Japanese company not long ago who was selling substandard steel as inspected and certified top quality?
Is this why President Trump is re-building American steel?
So we can trust what is built with it, instead of suddenly being killed by it?
No. Post-tensioned. With light weight concrete, per the first news reports. I suspect individual components may have been pre-stressed prior to being assembled together via the post-tensioning process, however.
I was thinking Chinese steel
I wouldn’t be surprised. I’m so tired of seeing cheap Chinese crap for sale everywhere. More than half the stuff on Amazon now is no-name Chinese stuff.
The US is becoming S. America where the elite can afford the best stuff (in our case, goods made in the US) while everyone else is left to buy cheap crap made in China. It makes me mad.
