(wiki-TODO: Explain relation to atomically precise manufacturing)
- pros: cheap
- cons: crude, just structural, just compression
In erection and removal: not reversible without destruction (exception loose interlocking concrete tiles), dusty, loud, time and energy intensive, big CO2 emittant
- Common minerals in "concretes" like CaCO3 maybe interesting for atomically precise mechanosynthesis
Exotic forms of "concrete"
- Lime plaster (*)
- Gypsum plaster
- Sorel-cement (Magnesium based - very different)
- Geopolymers
- ...
