Sawdust specific weight: weight of 1 m³ by wood species
When wood is processed, small wood particles are formed: sawdust. Particle size depends on the type of tool used. Sawdust is considered waste from wood production, and its quality and other parameters are not specified in GOST standards. Therefore, empirical methods or tabular values are used to determine its weight.
Uses of Sawdust
Sawdust is widely used in construction, agriculture, and in the production of fuel pellets for heating equipment.
- Construction.
Woodworking industry waste, or sawdust, is used to produce wood-sawdust boards. They are used in the construction of interior walls and partitions and for flooring. Fine wood fraction is also used to produce sawdust concrete, thermoporite and other construction materials. Resins are used as binders, and the composition also contains antiseptic substances and flame-retardant additives.
Some types of concrete contain sawdust. Lightweight concretes such as sawdust concrete, wood concrete and gypsum-sawdust concretes contain woodworking waste as a filler.
Thermiz boards, consisting of sawdust, larger shavings and gypsum, are used as thermal insulation for walls, roofs and ceilings.
- Agriculture.
Sawdust is used as bedding in animal husbandry because it absorbs water well and is very inexpensive. Gardeners use it as mulch under plants.
- Abrasive.
Because of its abrasive properties, sawdust is used in some polishing processes, for cleaning floors in industrial premises, for cleaning carpet and fur products, as a grinding material for cleaning poultry at poultry farms, and in soap and carborundum production processes.
- Packaging and fillers.
Low weight and low cost make this material one of the most accessible options for filling voids when packaging fragile ceramic and glass products. As a filler, sawdust is used in the production of inexpensive plastics, porous brick and some types of roof tiles.
- Pellets.
Pellets as an alternative to conventional fuel have long been used in European countries and are gradually becoming popular locally. Pellet boilers with high heat output use wood granules as a convenient solid fuel.
Weight of Wood Sawdust
Depending on wood species and particle size, bulk density, or the weight of 1 cubic meter of sawdust, may vary.
| Wood species | Average bulk density (kg/m3) | Weight of 1 cubic meter of sawdust (kg) | Wood species | Average bulk density (kg/m3) | Weight of 1 cubic meter of sawdust (kg) |
|---|---|---|---|---|---|
| Acacia | 215 | 182-225 | Larch | 186 | 151-186 |
| Ash | 210 | 146-266 | Birch | 182 | 143-216 |
| Beech | 190 | 174-230 | Pine | 146 | 87-213 |
| Hornbeam | 213 | 207-223 | Chestnut | 182 | 168-202 |
| Oak | 227 | 193-288 | Pear | 188 | 164-199 |
Frequently Asked Questions
Can the density of sawdust be used for precise calculations?
The density and weight values for sawdust in this article are reference values. They are suitable for preliminary estimates, but design, construction, production and other critical calculations should be checked against standards, material datasheets or measurement results.
Why can the actual weight of sawdust differ from the table?
The actual weight of sawdust depends on composition, moisture, temperature, porosity, fraction size, material grade and measurement conditions. Because of this, real values may differ from the average table data.
How do you calculate the mass of sawdust from density?
For an approximate calculation, use the formula: mass = density × volume. If the density of sawdust is given in kg/m³ and the volume is in m³, the result will be in kilograms.
