The only "sawed" photos I've seen seem to show DIRT NOT CONCRETE inside of the steel posts.. Someone correct me if I'm wrong but does this look like CONCRETE to you?:

Looks like DIRT FILL not CONCRETE FILL! Is this a prototype wall or the actual wall? Actual wall is supposed to be CONCRETE NOT DIRT!!! The background of this photo would indicate this is a PROTOTYPE WALL, NO?

looks like a numbered prototype...

They might try sum gummy resin instead of brittle concrete.
