ps When I said Portland Cement weighed approx. 2500 lbs, I was
referring
to Portland Cement, I never said or hinted that one would put
2500 lbs
of Portland Cement into a yard of concrete mix.

Have you looked over your concrete mixes to see that it is very
common
for a yard of concrete to weigh approx. 4000 lbs?

One would not expect a PE to make sure a mistake.
No, it is not. Need proof? And if I show proof, will you admit
your
mistakes? And where is that 2500 pounds of Portland cement per
yard
used? Please show some criteria for your two tons, and your 2500
pounds
of Portland.

I tried to be helpful and show you many links showing you the
exact
weight of concrete, and the exact weight of Portland Cement, you
prefer
to ignore them. I didn't want you to continue with your
silliness, but
I should have known better. The question wasn't "is all concrete
4000
lbs per year", because there are light weight concrete mixes that
weigh
less, but as Bill said, concrete can and does weigh approx. 4000
lbs.
The fact that you fail to see this, does understand why you are
not
employed.
No, you are wrong. Bill actually said that concrete weighs 5000#.
Please show what facts you have that I am not employed, first. Now,
where WERE those links that you shown that states that there is
2500#
of Portland cement in a yard of concrete? You DO know, seeing how
you
are acting the expert here, that in reality, there's somewhere
around 5
bags @ 94 pounds in a typical 3,000 psi mix, for a total of 470#
don't
you? So, I'd really, really like to see this mix design that uses
2500#, because with a water/cement ratio of .53 maximum, you'd have
approx. 1,325 pounds of water. But you know this, right? Now,
here's
the thing. a yard of concrete is an AREA. This 2500# of cement
takes
approx. 12.72 cubic feet of area. The water that we need per ACI
307
would take an area of approx. 20.64 cubic feet, for a total of
33.36
cubic feet. You're now at more than a yard before you add in the
largest volumes, which are the coarse and fine aggregates, with
proper
gradation of course. So, for an F'c of 3000 psi, the aggregate
total is
going to be close to approx. 10 or 12 times the amount of concrete.
So
now you have a "yard" of concrete that is 400 or so cubic feet! So,
I'm
really confused. Please show me where you are correct, and I am
wrong.
Now remember something about that 4,000 pounds you are referring
to.
There is a factor of safety involved for that number. A cubic foot
of
normal weight concrete doesn't weigh 150 pounds, although that
number
is thrown around alot. The actual weight of normal weight concrete
is
around 125 pounds per cubic foot, or 3375 a yard. If you'll look at
ACI
guidelines you'll even see that there criteria uses 125# per cubic
foot
dead load for elevated slabs! And even THAT has a factor of safety.

Do you understand English?
Yes, I do. So, show me how you can get 2500# of portland cement into
a
yard of concrete using the criteria set forth by A.C.I. 307, A.C.I.
301, and A.C.I. 318. Do you also want me to post some design mixes
here
showing that I'm right and you are wrong about the weight of
concrete?
Also, do you want to show me how you get 150# per cubic foot, when,
following guidlines by ANY applicable code in the U.S., and ACI, and
even Factory Mutual, you only need to design a structure to resist
125#
per cubic foot?

Please go back and reread this thread before you respond. You might
be
able to understand the words if you read them a 2nd time.

I want YOU to tell me, in YOUR WORDS, how applicable codes, all ACI
publications that deal in the subject, Factory Mutual, as well as the
Steel Deck Institute, etc. all allow you to design elevated structures
that will resist the forces of concrete floors at #125 per cubic foot,
which equates to #3375 per yard. All of these use a factor of safety,
also. SO, how is it safe to do that, if concrete weighs #150 per cubic
foot, as you say? Tell me.


If you go back through the thread you will see that concrete's weight
can vary based upon the aggregate used. I am surprised that a PE does
not understand that. Now if you go back to the beginning of this thread
and read it very slowly you will have all of your questions answered.
They are all answered already.


I never ever said that a yard of concrete's weight doesn't vary. BUT,
you've stated that it's at 2 tons, that is wrong. I want YOU to tell me
how someone can, by all applicable codes, case studies, etc. be able to
design for concrete structures at 125# per cubic foot, when you say
that concrete weighs 150#. Also post any binding data that you have
that concrete weighs 150# pcf.



http://www.cement.org/tech/faq_unit_weights.asp

"Concrete: Concrete is a mixture of cement, coarse and fine aggregates,
water, and sometimes supplementary cementing materials and/or chemical
admixtures. A normal weight concrete weighs approximately 2400 kg/m3
(145 lbs/ft3). The unit weight (density) of concrete varies, depending
on the amount and density of the aggregate, the amount of air that is
entrapped or purposely entrained, and the water and cement contents,
which in turn are influenced by the maximum size of the aggregate."

Is that binding enough? And let's not quibble about 5 lbs/ft^3

Cubits per fathom furlong.


Sea horses?

Funny thing how even lab tests result in normal weight concrete at a
weight kevin claims it can't be. The whole world is wrong except for the
wannabe engineer from Atlanta. LMAO

Tell me about the first of your ancestors who came here.
Where were they
from? What countries?

I have direct Native American ancestors on both sides of my
family,
one within two generations. Which legally allows me to claim
Native
American status.

So with that in mind...

EVERYBODY GET THE HELL OUT OF MY COUNTRY!!!!!

So you're 100% Native American?

Didn't say that - I said legally claim Native American as my ethnic
choice. I suppose, although I've never looked into it, that I
could
also claim Hispanic also as one of the Grandmothers is Mexican.

Are you really saying that if anyone states that they have any
Native
American blood in them at all, that they can claim that status?
Where
ARE we going to put those millions upon millions of casinos?

And where did those Native Americans come from?

Mars.

Typical.......

lol, the Indian casinos can only be placed on Indian reservations.
Even
if you are 100% Native American, you can not open a casino off of the
reservation. Do you try to be so humorous or does it just come
naturally.

Show me that concrete mix design that has 2500# of Portland cement in
it, and weighs better than two tons, and we'll go from there......

Now, that's why I asked where are we going to put those casinos. There
is only so much reservation land. And I'm sure that all of us that
have
any tiny bit of Native American blood in us would like to open one up!
I sure would! I guess, seeing how I have just a trace of N.A. blood in
me, I'll go to Cherokee, NC and join that nation.

LOL,
The Cherokee Nation owns the reservation and they run the casino, it is
not up to each Native American to deciede if he wants to open a casino.

Have you still not figured that a yard of concrete can weigh over
4000lbs?

I know the FACTS about concrete. Do you need me to cut and paste some
mix designs for you to prove that a yard of concrete almost never
weighs two tons? Now, what about that 2500# of Portland cement in a
yard of concrete? Please provide some data to show this.

Now, as part OF the Cherokee nation, each individual has a say in it's
enterprises. But, you are forgetting the gist of the message here. Just
because someone has any little tiny bit of N.A. blood in them, doesn't
make them instantly able to be a part of such.



Read it again. He said Portland Cement weighs 2500# a yard. And to
be considered a Native American for a lot of fishing rights you have
to be 1/32. To be in on a casino you have be a member of the tribe.
There have been some real battles where part of a tribe decertified
another part.

I really do not believe he can read or understand English.


What is scary is if he has anything to do with designing structures when
he cannot grasp a simple fact like the weight of concrete.
