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
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.
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.

I'm laughing my ass off. I just stayed at Budget Inn in Herkimer NY and the
ceilings are cement block. Thus my reason for being here. You can Google the
motel and see photos for yourself.

Yes...I have personally seen a multi level structure with the load bearing
floors comprised of rows of block seemingly supported by the concrete poured

Having a great uncle that owned a block plant that actually made
"cinderblock" by hand it is a personal pet peve that bugs the holly
H%&* out of me when people call concrete block cinderblock.
What you are refering to posibally could be cinderblock because of the
age issue. Please note this comment is not directed at you but I wanted
to take this oppertunity to mention this. Even the home shows on TV use
this term and its just not right. Cinder blocks were actually mande
from cinders and looked nor performed (we know that now) nothing like
concrete block. "Cinder" block have not been made in this country for
more than 50 years yet there is a new trend (caused by the home shows)
at calling these concrete block cinder block. I have not doubt that
what you are refering to could infact be cinder block. To answer your
question without to much detail these blocks were laid on a wood form
supported from below by a series of posts or by a combination of posts
and beams. The block are then laid as you would lay brick in a side
walk or patio. They are of course filled with concrete......
I understand where you are coming from. I dont really know if the
blocks in question are cinder or concrete. I always thought cinder
blocks are the ones that have the "design" on the side that looks like
a rock or boulder, is that the case? I would guess the blocks in
question are probabaly concrete as the building was built in 1964. How
do the blocks support themselves after the wood forms are removed? Is
there any kind of beam running through the holes in the blocks to give
