Roman Concrete

Construction in Ancient Rome

• Volcanic ash, lime, and water were used in construction in ancient Rome.

Roman Concrete

• The main ingredient in Roman concrete was volcanic ash.
• The combination of volcanic ash and lime created a strong and durable binding agent.
• The addition of volcanic rocks and pebbles to the mixture added strength and texture.

Crack Prevention

• The unique property of Roman concrete that prevented cracks from spreading was the presence of volcanic ash, which reacted with seawater to form a strong and cohesive bond.

Widespread Use

• Roman concrete was in widespread use from the 2nd century BC to the 5th century AD.

Notable Structures

• Roman concrete was used to build structures such as the Pantheon, Roman Baths, and Aqueducts.
• The Pantheon, built in 126 AD, still stands today, with its concrete dome remaining intact and unreinforced.
