Concrete

Definition

Concrete is a building material composed of aggregates, water, and a binding agent, usually cement. It revolutionized construction techniques in ancient Rome by providing strength and durability, allowing for innovative infrastructure improvements, monumental temple architecture, and advanced brick and stone masonry techniques. Its versatility enabled the Romans to construct large and complex structures, making it a foundational element of their architectural legacy.
