Exploding Concrete

I recently came across a very interesting incident involving foam concrete.

Foam concrete is produced by mechanical mixing of foam prepared in advance with concrete mixture, and not with the help of chemical reactions. At the incident site, two workers were removing steelwork using angle grinders while the foam concrete was settling. There was an explosion injuring the two workers.

Foam concrete produces hydrogen which is highly flammable.
