## The secret of Ancient Roman concrete

UC Berkeley researchers have uncovered the secret behind the durability of Ancient Roman concrete. This concrete can self-heal its cracks through chemical carbonation.

## Chemical carbonation

Roman concrete reacts with carbon dioxide in the air to form calcium carbonate. This process fills cracks, preserving the structural integrity of the concrete.

## Difference from modern concrete

While modern concrete cracks and deteriorates over time, Roman concrete can self-heal. This property allows it to endure for thousands of years.

## Details of the research

The UC Berkeley team examined the microstructure of Roman concrete and discovered how the carbonation process works. These findings could inspire modern concrete technology.

## Future applications

The self-healing property of Roman concrete could lead to the development of more durable and sustainable concrete in the future, potentially revolutionizing the construction industry.

## Importance of historical heritage

Unraveling the secret of Ancient Roman concrete is crucial for preserving historical structures and developing new techniques in modern engineering.
