How Can Concrete Be Poured Underwater?

Seems incorrect information, the water is sucked out

Because that Video is wrong. First you set up the hull, then you pump the water out and pour the concrete in. After its settled you remove the hull and you got a bridge pillar

Wrong, the Water is always drained from the chamber

They use special concrete that doesn’t wash away. It hardens even while surrounded by water.

That’s a lot of concrete for stuffs like this

I think the question should be, how does it solidify under water?

They use a special type cement for underwater concretes.

Because concrete is not only drying out when it sets. The main process is a chemical reaction between the cement and water that’s already bound into the concrete mix. It’s called a pozzolanic reaction.

This is so educating for sure.

Wrong.

Wow I've trying to discover that over the years

Waw

i dont get it. the cement is being mixed with the water even after the tremie thing

Its wet

I've always been curious about the specifics of this. Thanks for the video

@grok verify

ee nasıl sert kalıyor da cıvık olmuyor

You're wrong

Cofferdam....Tomlison that year🤦‍♂️😊

Reminds me of Well Completion & Cementing for deep water oil wells

hard to believe it works.......

i learned

I don’t think this how 3rd mainland bridge pillar was made , it’s still a mystery to me how bridge was built on that huge water

This is brilliant 👏

sets underwater somehow?

You’ve gotta be very careful about misinformation online.

Tremi ile çelik kalıbın dibinden başlayarsk dökülen beton sudan etkilenmez suyu kalıbın dışına iter

This is new.

Very possible.
