Technological Properties of Cement-Bonded Composite Board Produced with the Main Veins of Oil Palm (Elaeis guineensis) Particles

Abstract

The effects of main veins of palm (Elaeis guineensis) particles and the amount of CaCl2 on the mechanical and physical properties of cementbonded composite boards (CBCBs) were investigated in this study. Homogenous CBCBs were produced with main veins palm particles content at three levels of 10, 15, or 20 wt.% and CaCl2 at three levels of 0, 3, or 6 wt.%. Other manufacturing parameters consisting of pressure and time for cold-press, material dry weight, and panel dimensions were kept constant. The flexural strength, flexural modulus, internal bonding, water absorption, thickness swelling, and the thickness of CBCBs after 2 and 24 h immersion in distilled water were determined. The results indicated that increased amount of lignocellulosic particles caused a decrease in the mechanical properties of the CBCBs. The increase in calcium chloride up to 6 wt.% improved mechanical properties of the CBCBs. The panels manufactured with 10 wt.% E. guineensis particles and 6 wt.% CaCl2 showed the most favorable physical and mechanical properties.

Investigation of the usability of apple tree pruning chips as an alternative raw material to produce cement bonded particleboard

“…Literature concerning the utilization of woody materials in the production of cement-bonded particleboard is scarce. Grapevine stalks [11] pruning of Acacia salicina, Ficus altissimo, Pithecellobium dulce, and Tamarix aphylla [12] date palm fronds and pruning of buttonwood [13], oil palm veins [14], sunflower stalks [15] have been investigated for their suitability for the production of cement bonded particleboard and found technically appropriate. Most of the references given above-used pretreatments such as cold or hot water to the particles in order to overcome inhibition.…”
