Roman concrete - Wikipedia
Roman concrete, like any concrete, consists of an aggregate and hydraulic mortar, a binder mixed with water that hardens over time. The composition of the aggregate varied, and included pieces of rock, ceramic tile, lime clasts, and brick rubble from the remains of previously demolished buildings. In Rome, readily available tuff was often used as an aggregate.
Gypsum and quicklime were used as binders. Volcanic dusts, called pozzolana or "pit sand", were …Wikipedia · Text under CC-BY-SA license- Estimated Reading Time: 9 mins
