It seems cinder blocks haven’t been used for construction (exterior walls) for about 50 years when mass production of them stopped. Back then coal was commonly used for fuel so there were a lot of cinders available. They are sometimes used for interior walls – lighter and cheaper.

So the term “blocks” when talking of construction in the US if the house is younger than 50yrs are concrete, made of cement, sand, water and aggregates (sand, stone or similar).
Another term for them is CMU’s – concrete masonary units.

We learn a little every day. 🙂
