Which is stronger cinder block or concrete block?

Lack tensile strength so don't hold up against pressure, and are less durable. Greater tensile strength, withstand pressure and force. Blocks are more 'flexible' and can bend under pressure – prohibited in some construction by building codes. Much stronger and more durable than cinder blocks.

Are cinder blocks concrete or cement?

Cinder block is made of concrete and cinder. Concrete block is produced from steel, wood or cement. Cinder block is lighter than concrete blocks. Concrete block is heavier because it contains stone and sand.
