CEMENTED CHIP BOARD AND MULTILAYER CEMENTED CHIP BOARD

摘要

PROBLEM TO BE SOLVED: To provide a cemented chip board having excellent dimensional stability. SOLUTION: The cemented chip board consists essentially of cement, wood chips and inorganic aggregate and is produced from a composition obtained by adding 10-25 pts.wt. of wood chips, 15-25 pts.wt. of inorganic aggregate having 1.2-1.5 bulk specific gravity and a <=200μm average particle size and 20-30 pts.wt. of inorganic aggregate having 0.6-1.0 bulk specific gravity and a <=50μm average particle size, to 100 pts.wt. of cement.
