OT Concrete weight?

Oh mighty WERA BBS, Help.

I need some concrete density info. I need to ballpark the total weight of something with X amount of standard, plain aggregate concrete.
Who has an average XXXXX lbs per yard or YYYYY lbs per cu ft of concrete?

Thanks,

 

Man, I used to know this stuff but it's been so long since I've thought about it.

You have any concrete plants in your area? Call them and ask one of their PM's/ engineers (if they're worth a crap, they'll have a few).

What are you trying to place on your slab?

 

Roughly 150 lbs/cf

 

Normal weight concrete is about 148lbs per cubic foot. Lightweight can get down in the 120s I think.

Not on slab. Think if i had a box (eg. 10'x2'x3') and filled it with concrete how much would it weigh? Or what size box would I need to overcome the natrual floatation of a man sized object?

Need to make concrete "boxes", and know what they will weigh, roughly so I have enough gumbas, errr forklift to pick them up.

edit:
I love this place, as I was typing, the answer appeared.

Thanks Guys.

 

If you're trying to hide the evidence, posting here was not a great idea.

 

Go with 150 lbs per cubic feet suggested above.
You cannot go wrong. This is the typical value used.

 

shame people still are unable to use google....

first link:
http://hypertextbook.com/facts/1999/KatrinaJones.shtml

McGraw-Hill Encyclopedia of Science and Technology. "Volume generally assumed for the density of hardened concrete is 150 lb./ft3. (2400 kg/m3)"

three links down and you get a nifty calculator:

Whats a google? Is that like AOL?




I did search but didnt find any info.

hmmmm, I call BS. :tut:

 

What's the point when you can just "ask WERA".

 

Bad idea....Concrete preserves the body, lie (sp)

 

Yep, 150lbs per cubic foot is what we use when estimating waste cost for radioactive cleanup jobs.

 

Some people just make a simple task harder.

 

Feet can still identify a body. You people are sloppy.

Mongo you are officially off my list of people to kill other people with.

 

And in case you were wondering a cubic foot of depleted Uranium weighs a mere 1200lbs.

 

Go get a wood chipper. Whoooooooosh!

 

When they find a bunch of racers on the bottom of the 'hooch they will quickly put 2 and 2 togther.
