| Abstract | Value-added cement-bonded particleboard (CBPB) was fabricated using processing residues of Masson pine with Portland cement as a binder. Effects of cement-wood ratios and particle lengths on the integrated performance of CBPB were investigated. It showed that Masson pine had a good compatibility with Portland cement, as reflected by a compatible index 83.5% (i.e., greater than 68.0%), which indicated that the Masson pine residues are suitable for manufacturing CBPB. Besides, the physical-mechanical performances of CBPB strongly depended on the cement-wood ratios, and higher cement-wood ratios resulted in the CBPB produced with higher physical and mechanical properties (i.e., greater density, higher modulus of elasticity, enhanced modulus of rupture, increased internal bond strengths, and smaller thickness swelling). However, the particle length of the wood residue was found to have a limited effect on the integrated performance of CBPB. The study also revealed that the thermal conductivity of CBPB increased with the increase of the cement-wood ratios and the particle lengths. Our work herein opens up a new strategy for promote a circular economy by upcycling the wood processing residues into CBPB with admirable comprehensive performances. |
