Seawater Intrusion in Tunnels Found to Accelerate Concrete Decay via Bacterial Biofilms

Concrete in road tunnels decomposes unexpectedly fast

When seawater penetrates concrete in road tunnels, a biofilm is formed that breaks down the concrete. This can lead to high costs and the risk of damage if stone and concrete drop from the tunnel roof. In a new study, led ...

Study reveals mechanisms behind decomposition of concrete in road tunnels

In a recent scientific publication, the researchers have discovered new insights about the microbiological processes behind the degradation.
