Concrete blocks are constructed from pure concrete. That is, the aggregates that are used are finely crushed stone or sand.
Cinder blocks are also created from concrete, but the aggregate includes either coal cinders or ash. Consequently, cinder blocks are much lighter in weight than concrete blocks.
|Since I don’t have any intention of actually using the blocks to build something .. a wall .. a building .. I like the idea of using them for detailing a scene.|
