Thanks Kris. As someone with a shopworn degree in biology this raises intriguing questions. Have to look into it!

So this is the result when someone poops into a concrete mixer?

I'm wondering about decay... and won't this bacteria have a life span?

Presumably it just breeds...like the stuff they find inside rocks in Antarctica.
My kind of Bio-concrete...a chocolate Reichstag.

What I see is the CaCO3 fills the voids, creates a temporary barrier against liquid water intrusion, but is susceptible to long term degradation. This may be more economical than specially treated and coated steel reinforcement, such as polymer coating, which is an option. Stainless steel reinforcement bars and galvanized are other options. There are pretreatments for concrete to enhance water "resistance".
