Concrete

Definition

Concrete is a construction material composed of cement, water, and aggregates such as sand and gravel, which hardens over time to create a durable structure. In early Roman architecture, the innovative use of concrete allowed builders to create larger, more complex structures, leading to advancements in urban planning and architectural design.

5 Must Know Facts For Your Next Test

1. The Romans perfected the formula for concrete, allowing them to construct massive structures like the Pantheon and the Colosseum that have stood for centuries.
2. Roman concrete had superior durability compared to modern concrete due to the inclusion of volcanic ash, which helped it withstand harsh environmental conditions.
3. Concrete enabled the construction of large-scale public works projects, such as roads and aqueducts, greatly improving urban infrastructure and connectivity.
4. The flexibility of concrete allowed architects to design complex shapes, including domes and vaults, revolutionizing architectural possibilities.
5. The use of concrete in ancient Rome laid the groundwork for modern construction techniques and remains a fundamental material in building today.

Review Questions

• How did the introduction of concrete change Roman architectural practices?
  • The introduction of concrete transformed Roman architectural practices by allowing for the construction of larger and more complex buildings.
