clinker

Thinking back to the clinker paths (perhaps clinker isn't coal-y enough though) that have been ripped up and re-planted, they did seem to be moister than the rest.

Yeah if you're calcining concrete clinker you'll happily use resistive heating if electricity is cheaper than nat gas.

When you're driving through North Dakota and see the red clinker in the cliffs along the highway...

It can understand preprocessor macros, and the FFI's CLinker class understands different platform ABIs.

He was freed but Bradley Manning got 30 years in the clinker.

Other ways of tackling cement production related emissions are less CO2 producing alternatives to clinker, and even reusing old concrete panels in new construction.

And even in places like Germany or Denmark where it looks like brick, it's often just a clinker façade over a timber or frame structure.

Or, how about taking an existing cement plant and have it use the air heat-exchanger/turbine/generator setup described in this project to recover the energy in the red-hot clinker?

That's what the `CLinker` class is responsible for.

I don't know what clinker from salt mines looks like.

> Years ago, during fieldwork on the major buttes of western North Dakota, John Hoganson and I discovered clinker pebbles in the Arikaree Formation indicating that coals had been burning prior to when these rocks were deposited some 25 million years ago.

Fossil fuels, meat agriculture, open clinker refinement, and more will have to change, and there is an urgent need for bio carbon capture and sequestration (CCS) at scale that isn't anything remotely like #TeamTrees that actually takes carbon from the atmosphere and disposes of it somewhere safe for millions of years in an economical manner (preindustrials levels can be reached for under $25-30 T).

According to the article, the clinker has the same composition as the "normal" one.

No, they sub it for lime flux, which had the side effect of reactivating the cement (makes “clinker”), which can then be used again in new concrete.

The article makes it sound like we get the clinker "for free" because the energy input is required to make steel anyway, but there is no word about whether it actually needs the same amount of energy with the added slag, or more.

> It's an exaggeration to claim that ballast would have been used for railway tracks for centuries "At Whitley in 1704, when the word first occurs in a railway context, clinker from the salt-pans was used 'for the ballast of the waggonway'"[1] By my reckoning, 2023 - 1704 = 319 which I think comfortably fits into "centuries"?

Clinker manufacturing for cement and concrete is amongst the worst offenders.
