Graphene in 2020s: Concrete additives
Read the condition on Graphene before the nickname. Year 2020s, line “Concrete additives,” figure 2004. Dose-sensitive marketing vs independent tests. A material is what it is made of, the condition it survives, and where it goes afterward. Graphene under “Concrete additives” in 2020s should say which, with 2004 tied to the condition. A figure with no condition is a boast. Readers meet the name on the back of a product, so the code and the history should not share one sentence.
Scores compare Graphene with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates. Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number.
This atlas treats Graphene as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: ~3000–5000 W/m·K in-plane (theory/exp bands). Insulation score 18/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: carbon; not a building product. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.
Origin: Geim & Novoselov 2004, Manchester. The process chapter follows feedstock → conversion → forming → finish → install. Uses span buildings to defence / safety. Pairings matter: carbon-fiber. Circularity mark 42/100. Ask which scrap, which certificate, which year. Related atlas entries, a short glossary, and three threads that keep Graphene honest.
The label keeps Graphene, 2020s, and 2004. “Concrete additives” is the condition on the figure.2020s
