Scenarios about 'roman concrete'

The unique building material used by ancient Romans that enabled the construction of durable structures like the Pantheon and Roman aqueducts. Roman concrete (opus caementicium) was remarkably waterproof and became stronger over time due to its unique chemical composition including volcanic ash, lime, and seawater. Its durability and versatility allowed Romans to construct architectural marvels that have survived for millennia, presenting fascinating possibilities for alternate technological development paths.
