Mr. Despair posted:I did some looking the last time it came up, and there are companies advertising transport casks that have heat losses on the order of 3 C an hour, so there's probably a pretty decent margin there. quote:Refractory lining is 5" thick light weight 60% alumina castable capable of 3000° F. Heat loss ia approx. 45.5° an hour. More than 3C/hr, but still seems manageable.

Seems like the hot aluminum would make the asphalt sticky enough to make removing it problematic. It looks like it doesnt fuse, if you look at this picture you can see some of the hardened aluminium has already separated from the road:

Re: the aluminum transport talk, you guys know how cement trucks work, right? They mix cement and water at the plant and then the truck has to get to the job site and unload within a specific amount of time. A serious delay and the cement hardens inside the mixer. And then you either scrap the entire mixer tank, or some poor fucker has to get in there with a jackhammer, probably violating a bunch of OSHA regulations about working in confined spaces. Anyway, point is, there are other areas where "deliver this on time or else the truck is ruined" is a thing.

Not sure how this is OSHA related at all and looks aside.....it's probably Cor-ten steel. Cor-ten,although it looks rusty, actually develops a protective patina and can last for a very long time.

bustercasey posted:This building in my area was just finished. I don't understand the rusty metal shingles. Looking at that much rust makes me cringe. I guess they used weathering steel? The idea is to get an alloy that generates a uniform, unbroken patina that then acts as a barrier against further corrosion. It doesn't also work so well, though. Pictured: Atlanta's Omni Coliseum, which looked like the base of one of the lovely SimCity arcologies.

Platystemon posted:Can’t you “poison” the cement with sugar to prevent that? Yes, but it'd never come to that unless someone really screws up. When a load on concrete gets to the job, someone's supposed to inspect that poo poo and the number of turns the barrel's rotated is written down on the inspection report. If it's spent too long in transit it's been agitated too much and won't cure right so that load gets rejected and dumped. Or if people aren't doing their in right it gets accepted and poured. But in neither case is it going to sit in the drum until it sets. Again, unless someone really screws up. Which never happens. But that's like a driver-gets-drunk-drives-to-Vegas-and-passes-out level of "screwed up."

Asphalt trucks have similar considerations for cooling. It's delivered with dump trucks and has to be laid down within 2 to 3 hours.

They mix cement and water at the plant and then the truck has to get to the job site and unload within a specific amount of time. A serious delay and the cement hardens inside the mixer. Typically you just dump it in a ditch then use your on-board water reservoir to clean out the insides before that happens. I've seen the end result of an idiot who worked for Lafarge and forgot to turn the drum on. Dude drove for an hour, arrived at the site, dumped a little in the forms, the contractor refused to accept it because it was too hard, and then the idiot drove back to the depot (spinning the drum of hardening concrete), looked at his watch, saw it was 12:00, turned off the truck, went for lunch, and arrived back at work in time to get fired. That drum was almost a-write off, but they had a special super high-pressure, pressure washer for just those occasions (thing can slice cinder blocks like they were Styrofoam). They didn't even need to take out a hammer.
