Abstract
A study was carried out to investigate the
suitability of the maize cob (Zea mays) for particle
board manufacture. The purpose was to examine
general limits within which a satisfactory board can
be made with this agricultural residue.
The maize cob was found to consist of pith,
wood-blast and cortical layer or chaff.
Samples of particle board were produced from the
maize cob collected from farms around Samaru Village.
A liquid resin of "Gum Arabic" was used in six
concentration levels: starting from 9, 10, 11, 12,
13 and 14 percent based on the oven-dry weight of
maize cob particles. Some selected physical and
mechanical properties of the boards were evaluated.
The results were compared with the data available
from the present standards. All samples satisfied
the standard requirements except for "water absorption"
and "thickness swelling" tests. This may be due to
non-addition of wax during the manufacturing process.
It was generally observed from the results that the
maize cob is a good material for particle board
manufacture and its properties were consistently
dependent on the resin concentration levels and
density
