ABSTRACT
Technological of cement board developed so thatall industrial
disposal of wood specially in the form of changeable lignoselulosa become
material which is good for human prosperity. The waste upon which cement board
will obtain double advantage this lessen the expense peculiarly and obtai an
substance with the higher economic value. This research aim at knowing the influence of treatment of waste of
particle and proportion of cement adhesive
to nature of cement board which is made of
by a industrial disposal wood.
Factorial experiment arranged in a completely randomized design, with the test continue the
Tukey. Factor used in this research is consisted of by the treatment of
particle waste ( without treatment, cold soaking and hot soaking) and
proportion of cement ( 150%, 200% and
250% from substance weight). Parameter measured were : water content, specific
grafity, modulus of repture, modulus of elasticity and thick reduction effect of pressure 3 kg / cm2.
Result show that the treatment of waste of particle and proportion
of cement to give the very real
influence to nature of physics and yielded cement board mechanics. Nature of
physics and board mechanics cement from industrial disposal of wood of specific
grafity, modulus of repture, modulus of elasticity fulfill the standard which
qualify the DIN 1101.
Key words : Cement board, industrial disposal, treatment of waste, proportion
of cement
