On: Bacteria and sand engineered into living concrete

[jbotz]

A lot of concrete is used for making standardized "pre-molded" parts (blocks, panels, structural elements) and those can absolutely by made using a much slower process, stocked and then rapidly assembled during construction.

I'm often dumbfounded when I see building with cast cement only to be broken down with cranes later. Is it stupid (unstable) to make cement blocks and build by stacking most of them (maybe keep pillars and floors cast). So you can reuse them.

As a counter, do you want to buy a brand new Tesla made with "100% recycled parts from former cars!"?

I'd buy a refurb at a refurb price. My car is 10 years old and still running great so I can't imagine a refurbished newer vehicle running any worse.

There are no refurb skyscrapers. Noone wants a transmission with 185,000 miles on it in a "new" car, just like a developer doesn't want a concrete form that supported 40 floors above it for 20 years in his "new" construction.

But I meant blocks that were mostly under simple compressive load, not slabs. Would they still age bad ?
