Researchers from Lawrence Berkeley National Laboratory have studied Roman concrete marine structures to find why they last for thousands of years and are stronger now than when they were first constructed while modern marine concrete structures crumble within decades. They found that the seawater filtered through the material adds cohesion and strength through interlocking minerals. Modern concrete is designed to be inert, while Roman concrete is more flexible and durable, giving it its longevity. The researchers are investigating how to replicate the ancient material today.
