Eddie Concrete Inspection

Big Eddy here. Inspecting this gorgeous concrete specimen. Before someone makes me send it back to the Protected Zone!

Looks like a...frothy volcanic aggregate...maybe tuff from volcanic bombs? And the binder is...ooh, quicklime. How would you make quicklime underwater? Melt shells in lava? I bet it gets stronger with age. They built to last. Which you'd have to, in the ocean.

There's a tarry cement in the mix...ah, but no matter how I sniff, I only smell bottled air. Maybe it's for crack healing. And...oh, wow, look at that. A live culture! That's bacterial action! The rebar in this concrete was alive. Maybe they started by growing bacterial fibers, like a wire blueprint, and poured the concrete over it...

I can't get enough of this. I have to get over to the Protected Zone.
