Stalactites at Cape Point toilets

Unread post by RUG » Sun Sep 04, 2016 12:32 pm

Hi there!
I saw these "stalactites" hanging from a concrete overhang at the toilets at Cape Point. I thought it was quite a strange place to find them, especially considering the fact that the concrete from which they are hanging can't be too old. So I'm wondering what these are composed of. I thought maybe salt from the sea water. Does anyone have an idea?

RUG, I have seen that before in other cement structures and my guess is its the calcium in the cement leaching out and forming those stalactites, but also open to other suggestions! :?
