Keg weight question...

[Ryan Wells]

I have a sand filled keg that weighs in at 240. I know concrete would get me somewhere over 300, but can anyone tell me what wet sand would yield me? Should I pre-mix it in a wheel barrel first or just alternate filling the keg with sand/water as I go? how much water?

Thanks!

Various items and densities you could commonly use to fill one are as follows:

Water @ 64 lbs/cubic foot
Sand @ 100 lbs/cubic foot
Mortar mix @ 130 lbs/cubic foot
Concrete @150 lbs/cubic foot

IMO, if you want a keg in the high 200's, i would remove the valve, pour in dry mortar mix, and add water inside the keg. Take a small piece of rebar and do a halfway job of mixing it. Much easier than trying to pour wet mix down that small hole and lots cleaner."

I think if you don't mind taking your time, you should be able to just pour water in on top of the sand. Water will always sink through sand, think of the beach. It may not be a quick process though. You should be able to add quite a bit of weight though I would imagine.

Thanks guys. That helps.

If you new the average size of each grain of sand, you could then calculate the void fraction and then the amount of water you could add to a keg full of sand. Or you could just pour water in until it was full :D.
