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.
