Concrete blocks. Though history records the use of concrete blocks by the Romans, Greeks and even Egyptians (some of the two-tonne blocks that make up the Pyramids are believed to be a primitive form of concrete), modern-type blocks were first cast, albeit in modest quantities, in around the middle of the nineteenth century.
