In some older buildings, usually small buildings in the basement or
below a flat roof, there was a cinder block ceiling- with cinder blocks
just like on a wall. Has anyone heard of this before, and if so, how
did they support the cinder blocks, and mortar them together despite
gravity?

No, I've never seen a cinder block ceiling/roof (although which do you
mean?)
Poured concrete, yes, even for a relatively small structure, but never
block.

Would have to have had a support frame of some sort to have done such,
but it doesn't sound like a good idea to me however it might (if it
actually was) have been done.

I will take a picture at one such building I am aware of which has it.
The building I am aware of is a private pool club of which I am a
member. The room with the block ceiling has a flat roof above it, so
my guess is that the blocks are the ceiling below, and the substrate
for the roof above, which is a tar/ruber roof.

Interesting.
How do you tell the difference and are they as strong as concrete block?

I have never heard of a cinder block ceiling.
One is actually made out of cinders and are almost black and the
other is white as in concrete. Used to be common back when I was
starting. No they are not as strong. Haven't seen one in years.
