Flax shive and hemp hurd residues were characterized, and the feasibility of manufacturing three-layered particleboards was evaluated using 2.5% and 5% polymeric diphenyl methane diisocyanate resin loadings. The flax shive and hemp hurd residues had lower bulk densities and higher aspect ratios compared with the wood residues. Their higher aspect ratios offered greater overlap in bonding, which led to consistently higher bending properties that exceeded the American National Standards Institute (ANSI) requirements for low-density (LD2) particleboard and, in some cases, medium-density (M2) particleboard. Because of their particle geometry, the flax shive and hemp hurd particleboards also showed minimal linear expansion with changes in the moisture content at 20 ± 3 °C and between 50% and 90% relative humidity. The high absorption capacity of the flax shive and hemp hurd residues resulted in higher thickness swell and water absorption properties than the wood residues. The results indicated that low-density flax shive and hemp hurd particleboards (500 to 620 kg/m 3 ) can be manufactured using isocyanate resin quantities as low as 2.5% to produce panels that conform to ANSI specifications with a greater mechanical performance than that of wood residue particleboards.

“…Agricultural wastes such as sugarcane bagasse, arhar stalks, date palm midrib, flax, babacu shell, vegetable fibers, vine stalks, wheat straw, and rice husk ash have been used as filler in the manufacture of wood-cement boards (Aggarwal 1995;Almeida et al 2002;Ntalos and Grigoriou 2002;Papadopoulos and Hague 2003;Roma et al 2008;Nemli et al 2009;Nasser 2012;Bahurudeen et al 2015). These raw materials have been used as substitutes for mineral aggregates and solid woods from natural forests (Savastano et al 2000;Karade et al 2001;Almeida et al 2002;Semple et al 2002;Li et al 2004;Abdel-Kader and Darweesh 2010).…”

“…The effects of extractives can be overcome by adopting suitable measures such as cold water extraction and/or using an accelerator such as calcium chloride (CaCl2) (Almeida et al 2002;Okino et al 2004;Aggarwal et al 2008;Olorunnisola 2009). A dose of 2% CaCl2 by weight of cement inhibits the adverse effects of 1% extractives of arhar stalks (Aggarwal et al 2008).…”

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.
