Asphalt?

[jhncp]

I got a 55 gal drum of black stuff at an auction, at first I thought it was steel but it's non magnetic, my next guess is asphalt?

Coal Slag for sand blasting?

That would be my guess too.

I don't know about coal slag but that sure looks like a blasting media.
Could it be aluminum oxide.

Appears to me that it could be a sand blasting media called Black Beauty. Very popular with headstone engravers.

Put a handful in a steel pail gravel place or such try and light it if it burns could be used floor dry if not then probably the media.

I'm wondering how you are going to mix it with hot tar to be able to use it.

Asphalt is the tar like substance, not the aggregate.I

Look it over with a microscope or magnifying glass to see if it is a solid or or bubbly like lava rock.

Looks like Black Beauty to me too.....

With as harof time as I am having getting rid of chemicals and such at work, I dont recommend buying anything from auction unless youre 100% positive you know exactly what it is before you bid on it. I dont have a clue what that stuff is. Someones probably really happy they got rid of it.

url=https://www.aciindiana.com/blog/what-are-recycled-asphalt-millings/]Asphalt millings (link)[/url] will partially dissolve in mineral spirits, diesel or gasoline. A small amount of millings will make a black solution or sticky mess depending on how much solvent you use. It should happen right away. A teaspoon of each is plenty to test and can be tossed back in the barrel and stirred in to get rid of it.

It does look too fine for asphalt millings. My guess would be grit blast media or waste casting sand.

I have 20+ tons of asphalt grindings sitting in a field right now and it honestly looks nothing like that. It more resembles pea gravel in size,
