KUALITAS PAPAN SEMEN DARI PARTIKEL SERUTAN PENSIL DENGAN BERBAGAI RASIO SEMEN DAN PARTIKEL
ABSTRACT: Cement-Bonded
Particleboard made of pencil shaving industry waste has not developed in
Indonesian. The main objective of this research was to evaluate the physical
and mechanical properties of cement bonded from pencil shavings particles and
determine the optimum cement-to-particle ratio. The treatment of
cement/particle ratio were 90:10; 85:15; 80:20 and 75:25. Methods of this
research were two steps curing. The first step was air curing using cold press
for ±4 days and continued of second step was oven curing at 80̊ C for 24 hours.
The result of the research showed that cement-bonded particleboard produced
density value around 0,73-1,13 g/cm3, moisture content 8,37-12,16%, water
absorption on immersion 2 hours and 24 hours around 23,78-43,48% and
27,33-51,90%, thickness swelling on immersion 2 hours and 24 hours around
0,79-1,82% and 1,39-2,89%, modulus of
elasticity around 114,21-880,17 kg/cm2,
modulus of rupture around 7,32-18,52 kg/cm2 and internal bond around 0,88- 1,56
kg/cm2. The effect of cement/particle ratio on the research showed that 80:20
is very good compared from 90:10; 85:15 and 75:25.
