Cement - A swim through the Coega Harbour Wall

I took this clip some time back. I was freediving on the wall - that's my speargun you see in front of the camera. You even see a few musselcracker there in the wall.
Imagine the hydration reaction calcium aluminium silicate taking water into its structure and getting stronger - and it still continues today, even through it is very slow.

The gradual hardening of cement is a true everyday reaction.

I my next chemistry post I plan to focus on rubber and a bit of chemistry related to rubber and its use.
