Cement, making it cleaner

[BeyondKnowledge]

Not really, the cement's pH is very high and protects the iron/steel. But it needs to be airtight, otherwise the moisture will enter and corrode the iron/steel.

Exactly, that is why epoxy coated rebar is being banned. The epoxy coating gives passages for moisture and air to make the metal rust. This makes the concrete split from the metal swelling from the rust. It also concentrates any chemical action to any cracks in the epoxy instead of curing evenly as with uncoated rebar.

Many modern concretes use plastic fiber for reinforcement. The plastic recycling company I worked for also made reinforcement packs for a while. They were a small paper bag with a weighed amount of short metal strips and one or two bundles of plastic fiber. It depended on the order for the one or two. 

So yes, plastic is structural and will be released from concrete in the future as micro plastics.  

Just another example of not thinking something through all the way.

First I've heard of adding plastic to concrete.

Not that i should be surprised i suppose.

Guess "plascrete" became a thing...

Wonder what it does to compression strength?

And is this why stuff is all falling to pieces in the likes of China?

But which generates more poawer 120 tons of coal or a short lived windmill? The windmills don't last as long as claimed and don't generate the amount claimed. How clean is a burning windmill. Many of them have burned.

They look better on the horizon than the likes of a coal or a gas-fired power plant...

I dont think anyone ever claimed they were fireproof.

But the truth is, the future lies with nuclear power plants...

And at some point, they are going to need to come to that conclusion.

I am hoping they finally get a working fusion reactor design before building a bunch of fission reactors. We haven't had a great history with fission reactors.

I mean thats holy grail...

I certainly hope so also.

But fusion is always 10 to 40 years away.

Then again, that's only true until it isn't. 

I think small modular fission reactors might be the way to go forward.

At least until the material science and/or magnetic confinement concerns are completely addressed with fusion reactors.

As you know, new designs seem to be materialising.

All it takes is for one of them to be viable and able to do more than break even.
