Biological durabilityof cement-bonded particleboard

IRG/WP 97-20115

Qiao Wang, M Takahashi

Cement-bonded particleboard (CBP) is a panel product manufactured from a combination of wood particle and cement with various ratio. The wood particle is used as reinforced material and the cement as an inorganic binder. Because of its many excellent properties, such as high weathering resistance, sound attenuation, and good acceptance for a range of surface treatments, CBP is widely used as a facade material in Japan. The present study is carried out to investigate the biological durability of CBP. The tested material was a standard commercial CBP product and obtained directly from one Japanese producing company. Two experiments were conducted. One was decay test by applying an Japanese standard method. The other one studied the effect of fungal attack on the internal bonding strength (IB) of the material. Two other commercial structural wood-based composites, i.e. Oriented Strand Board (OSB) and Medium Density Fiberboard (MDF), were also included in the study with the purpose of comparison.
