What does forensic science have to do with concrete? More than one might initially think!

When concrete structures display signs of damage that don’t align with their expected lifespan, the groundwork is set for a new episode of an exciting "concrete crime." In most cases, the cause of the damage is not straightforward. Especially when determining appropriate repair methods, identifying the actual cause of the damage is essential. And often, the question of liability also arises!

Concrete microscopy offers a unique diagnostic tool, analyzing the underlying damage processes and providing reliable forecasts about the remaining lifespan of the structure. Ideally, a thorough thin-section microscopy of samples from various parts of the structure should be performed to enable a comprehensive assessment of the current condition.

Examining the concrete microstructure is akin to forensic work, gathering evidence and clues. It can reveal information about the mix design, raw materials, processing errors, and issues such as inadequate curing, secondary processes, and crack formations. The concrete surface, in particular, provides vital information about the material's permeability or density, as well as potential interactions with the surrounding environment.

In upcoming posts, classic episodes of modern concrete "crimes" will be introduced. I wish you an exciting read!
