The genetically modified microbe has been programmed to swim down fine cracks in concrete and once at the bottom it produces a mixture of calcium carbonate and a bacterial glue. This glue combines with the filamentous bacterial cells, ultimately hardening to the same strength as the surrounding concrete and essentially “knitting” the building back together.
I see a Stephen King novel here. The microbes come under control of a remote, malicious entity and begin to destroy concrete rather than repairing it.
A triple win. A highly toxic substance, waste from coal plants, can be converted to a super durable, long-lasting, low carbon concrete.
[the concrete] can capture carbon dioxide, prevent the need for toxic dump sites, and be turned into a better, longer-lasting version of a highly in-demand product.
Hycrete admixture is waterproof concrete. No external membranes needed and it can be crushed then reused, rather than being dumped in a landfill.
Applications include deep foundation slabs and walls, podium and plaza decks, roof, parking and tunnel structures.
