study investigated the possibility of using the prunings of six locally grown
tree species in Saudi Arabia for cement-bonded particleboard (CBP)
production. Panels were made using four different wood particle sizes and a
constant wood/cement ratio (1/3 by weight) and target density (1200 kg/m3).
The mechanical properties and dimensional stability of the produced panels
were determined. The interfacial area and distribution of the wood particles
in cement matrix were also investigated by scanning electron microscopy. The
results revealed that the panels produced from these pruning materials at a
target density of 1200 kg m-3 meet the strength and dimensional
stability requirements of the commercial CBP panels. The mean moduli of
rupture and elasticity (MOR and MOE) ranged from 9.68 to 11.78 N mm2
and from 3952 to 5667 N mm2, respectively. The mean percent water
absorption for twenty four hours (WA24) ranged from 12.93% to 23.39%.
Thickness swelling values ranged from 0.62% to 1.53%. For CBP panels with
high mechanical properties and good dimensional stability, mixed-size or
coarse particles should be used. Using the tree prunings for CBPs production
may help to solve the problem of getting rid of these residues by reducing
their negative effects on environment, which are caused by poor disposal of
such materials through direct combustion process and appearance of black
cloud and then the impact on human health or the random accumulation and its
indirect effects on the environment.
