Karakteristik Fisis dan Mekanis Papan Semen Bambu Hitam (Gigantochloa Atroviolacea Widjaja) dengan Dua Ukuran Partikel
Abstract: Cement boards was
made from bamboo hitam (Gigantochloa
atroviolacea Wdjaja) using two particle sizes of 20 mesh
and 40 mesh.
The difference in
particle size thought
to affect the
quality of the
resulting cement board.
The purpose of this study was to evaluate the physical and mechanical
properties of cement board bamboo hitam using two particle sizes.Boards were made with size 25
cm x 25 cm x 1 cm with density of 1.2 gr/cm3 of two different particle size of 20
mesh and 40 mesh and each made in three replications. Cement board was made
with ratio of particles, cement and water in 1:3:2 and the addition of MgCl2
catalyst was 5%. In general, physical properties of cement board had completed the standard
JIS A 5417-1992, both cement board
particle size 20 mesh and 40 mesh.
Physical properties of cement board using particle size of 40 mesh
better than cement board using particle
size of 20 mesh. MOR value of cement board
using particle size of 20 mesh had met standard while the value of MOE did not
complete the standard. Internal bond
and screw holding
strenght did not
require in standard
JIS A 5417-1992. Cement
board using particle
size of 20 mesh had better mechanical properties than
cement board using particle size of 40 mesh.
