cellulose–hemicellulose–lignin
ChemistryBamboo is specified as cellulose–hemicellulose–lignin. Density band ~0.6–0.8 g/cm³ culm.
Bamboo · A fast grass culm sold as timber — scaffolding, flooring and a glue story that decides the indoor air.
Darker cells mean a higher score for this topic on that metric.

Declared reaction class in this atlas: untreated D-class typical; treated products vary. Assemblies still need resistance tests.
Thermal mark 40/100 versus the atlas. Conductivity note: ~0.1–0.2 W/m·K across the wall.
~0.6–0.8 g/cm³ culm
Origin story: ancient scaffolding; industrial strand board late 20th c. (East and South Asia).
Circularity mark 86/100 — editorial, route-specific.

What holds Bamboo together is not the nickname. Formula cellulose–hemicellulose–lignin, density ~0.6–0.8 g/cm³ culm.
Meters are atlas-relative. Grades are the SKUs buyers write.
Bamboo is specified as cellulose–hemicellulose–lignin. Density band ~0.6–0.8 g/cm³ culm.
Processing sets grain, crystallinity or fibre orientation — the reason two lots of Bamboo can test differently.
Coatings, oxide films, sizings or paper faces often decide weather and fire behaviour more than the bulk brochure.
Inclusions, voids, knots, pinholes or residual stress start the failures that mill certificates do not list.
Bamboo is a family. Grade names below are the ones buyers actually write on RFQs.
Moisture, UV, creep, hydrogen or carbonation shift properties in service. Design to the aged state.
Strength is an editorial 0–100 mark relative to the other 31 materials in this atlas — not a laboratory certificate.

Scaffold, furniture, Guadua.
Nodes visible, flooring.
Narrower grain look.
Dense, resin-heavy.
Heat or chemical, still not a fire certificate.
Bamboo holds together by ionic/covalent networks.
Hydrogen bonds, van der Waals stacks or grain-boundary cohesion set toughness and moisture uptake.
Fillers, fibres, plasticisers or aggregates are part of the real product, not impurities.
Oxides, chars, sizings or paints are the layer the world actually meets.
Change the grade, the coating or the moisture and you have a different material with the same English name.
Frozen silicate liquid — windows, bottles, fibres and a Euroclass A1 skin that still shatters and melts in fire.
Overall 58 💎Crystalline oxides and carbides for heat, wear and electronics — not the mug on the desk.
Overall 64 🏗️The hydraulic ceramic of cities — cement, water, rock and usually steel, with a fire story better than exposed steel.
Overall 57 🌲Anisotropic cellulose composite grown as trees — carpentry, mass timber and a combustible story that codes still manage.
