PHYSICAL AND MECHANICAL PROPERTIES

These properties can vary significantly depending on the origin and growing conditions of the wood.

  • Density *: 0.69
  • Monnin hardness *: 4.0
  • Coef. Volume shrinkage: 0.48%
  • Stability in service: moderately stable to stable
  • Total radial shrinkage: 5.6%
  • Fiber saturation point: 28%
  • Total tangential shrinkage: 7.3%

(*: 12% humidity)

NATURAL DURABILITY AND IMPREGNABILITY OF WOOD

  • Mushrooms: cl 1 – very durable
  • Dry wood insects: durable; distinct sapwood
  • Termites: class D – durable
  • Impregnability: 4 – not impregnable
  • Biological risk class: 4 – in contact with the ground, or fresh water

Due to a high silica content, this gasoline naturally covers the biological risk class 5 (use in marine environment or brackish water).

SAWING AND MACHINING

  • Blunting effect: significant
  • Teeth for sawing: stellate teeth
  • Machining tools: tungsten carbide

Very irritating dust. Sometimes clogging of the saw blades.

ASSEMBLY

  • Nailing – Screwing: good hold, pre-boring necessary
  • Gluing: correct

Tends to split when nailing. Gluing requires care (dense wood).

  • parquet
  • stairs
  • bridges
  • paneling

REACTION TO FIRE

  • French conventional classification: thickness> 14 mm: M.3 (moderately flammable) thickness <14 mm: M.4 (easily flammable)
  • classification according to euroclasses: D s2 d0 This default classification concerns solid woods meeting the requirements of standard NF EN 14081-1 appendix C (May 2006), used in vertical walls. Namely structural wood, classified, with a minimum average density of 0.35 and a minimum thickness of 22 mm.
