Uses
Cement-bonded wood fiber is used to manufacture a wide variety of products primarily for the construction industry (products like
insulating concrete form
Insulating concrete form or insulated concrete form (ICF) is a system of formwork for reinforced concrete usually made with a rigid thermal insulation that stays in place as a permanent interior and exterior substrate for walls, floors, and roofs. ...
s, siding materials and noise barriers).
Cement bonded wood fiber materials can be classified as low density, medium density and high density. The density of the material will determine to a large extent, the various properties of the end product. Other factors determining the overall performance of a cement bonded wood fiber material are:
# Wood particle type
# Wood particle gradation
# cement to wood ratio
# Level of sugar content in the wood particle at the time of bonding
Most common is low-density cement bonded wood fiber. It is known for its use in
