01 Feedstock
Ore, monomer, fibre, mineral or scrap that can legally become Hormigón.
Hormigón · La cerámica hidráulica de las ciudades: cemento, agua, árido y casi siempre acero.
Making Hormigón is a chain: feedstock, conversion (Roman pozzolana; Aspdin 1824; Hennebique RC), forming, heat, finish, install.

Cast, spin, weave, sinter, foam, laminate or coat — the step that sets anisotropy.
Temper, vulcanise, calcine or dry: skip it and the datasheet is fiction.
Coatings, sizings, facers, galvanizing, anodising, painting.
Fasteners, adhesives, DFT, compression, dryness — site quality is a material property.
Virgin route around Rome → Leeds → Paris.
Recycling exists but quality or energy often disappoints.
High-spec grades leave the commodity mill.
Coatings, sprays, casts — the factory is sometimes a jobsite.
Feedstock to installed product.
Energy in, class out.
Melting/softening does not melt; dehydrates and spalls; conductivity ~1.4 W/m·K.
Moisture, UV, chlorides, alkalis or oxygen — pick the one that actually kills Hormigón.
Fire class A1 is a starting letter, not a wall rating.
Process energy and scrap quality belong in the carbon passport, not in a footnote.
Líquido de silicato congelado: ventanas, botellas, fibras. A1, pero se rompe.
