Effect of Palm Lignocellulosic particles and calcium chloride content on MOR, MOE, and IB properties of wood-cement composite panels

In this research, feasibility of palm lignocellulosic particles application was investigated in the manufacture of wood-cement composite panels. The variable factors of this investigation were including palm lignocellulosic particles content in three levels 10, 15, and 20 % and calcium chloride in three levels including 0, 3, and 6%. The other factors consist of pressing compression, pressing time in 12 hour, dry weight, and panel dimensions (40×40×1.5 cm) were kept constant. The specimens were prepared from manufactured panels according to DIN 68763 standard and their mechanical properties such as flexural strength, modulus of elasticity, and internal bonding (IB) were measured. The results indicated that the increase of lignocellulosic particles content have been caused weak of mechanical strength of manufactured panels and the increase of calcium chloride until 6% level have been caused a gain of strengths. In this investigation, the panels manufactured with 10% content of lignocellulosic particles and 6% content of calcium chloride had the best flexural strength, modulus of elasticity, and internal bonding.
