I thought it was genius to make ships during WWII to make ships out of
"fullers earth" which was also known as "concrete.

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.

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.
