A new type of self-healing concrete is finally being used in the US. It can repair cracks without adding additional concrete.

Now researchers at Drexel University have demonstrated a type of self-healing concrete embedded with “BioFibers” that use bacteria to patch up cracks as they form.

‘Self-Healing’ Concrete May Have Preserved Ancient Roman Structures The durable material could fill its own cracks, new research suggests ...

Researchers in the U. S. have used synthetic lichen to develop a groundbreaking self-healing concrete system that autonomously repairs its own cracks using sunlight, air, and water, offering a ...

A damage-activated polymer layer may help extend concrete’s relatively short lifespan.

When micro-cracks occur, the concrete’s material reacts with water and carbon dioxide to form compounds that fill the cracks.

After casting, the Roman-inspired hot-mixed concrete samples were mechanically fractured and then re-mated (with a gap of 0.5 ± 0.1 mm) and preconditioned for the crack-healing studies.

Still standing: Researchers crack the secret of ancient Rome’s self-healing concrete Scientists have long wondered what made the material so durable. Now a new MIT study utilizing ...

In hopes of producing concrete structures that can repair their cracks, researchers are putting a new twist on an old trick for improving the durability of concrete. Fiber reinforcement has been ...

The problem spurred the Romans to develop and perfect a self-healing concrete that incorporated crystalline calcium.

In hopes of producing concrete structures that can repair their cracks, researchers from Drexel University’s College of Engineering are putting a new twist on an old trick for improving the durability ...
