コンクリート 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 コンクリート 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.

コンクリート (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.
コンクリート 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.
This atlas treats コンクリート as a system: mill route, coatings, tests and the cavity it sits in.
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.
Uses span buildings to defence / safety. Pairings matter: steel.
Producers below are landmarks, not an endorsement ranking. Prices are bands, not live quotes.
Circularity mark 30/100. Ask which scrap, which certificate, which year.
