Seven chapters follow. Fire and insulation claims name test families (Euroclass, ASTM E84, ISO 5660, KS F) rather than inventing a single safety number. Concrete is sold as grades, not as a single substance. Chemistry C-S-H binder + aggregate, density ~2400 kg/m³, heat band does not melt; dehydrates and spalls.

Concrete is one of 32 materials in this atlas, grouped under ceramics: history, structure, measured properties, process routes, uses, safety and market — not a product catalogue. Scores compare Concrete with the rest of the atlas on strength, heat, fire behaviour, insulation, workability and circularity. They are editorial, not certificates.

Conductivity note: ~1.4 W/m·K. Insulation score 22/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: A1. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.

Origin: Roman pozzolana; Aspdin 1824; Hennebique RC, Rome → Leeds → Paris. The process chapter follows feedstock → conversion → forming → finish → install. Concrete (C-S-H binder + aggregate) is a family of grades whose density ~2400 kg/m³, heat band does not melt; dehydrates and spalls, and fire letter A1.
