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

questions answered. They are all answered already.
Yeah, but what if I used styrofoam pellets instead of crushed
limestone as
an aggregate. Wouldn't that give me a very light, air entrained concrete?

There is a kind of "cement" they use to reduce the sound between floors
that they use a filler that is similar to styrofoam, and yes it is very
light.
