“…Environmental conservation and wood-based resource shortages have promoted worldly attention to abundant bamboo resources as a favored and sustainable building material due to its fast growth, environmental friendliness, capability of reuse, and its excellent mechanical properties comparative with those of structural wood products [1][2][3][4][5]. Bamboo-based construction engineering materials like beams, roof truss, and wall elements of residential houses has been extensively applied and further investigated.…”

This study employed the process of removing bamboo green and bamboo brooming from Neosinocalamus affinis in the production of laminated bamboo-bundle veneer lumber (BLVL) with a thickness of 28 mm. The effect of the removing extent of bamboo green on dimensional stability, modulus of rupture, modulus of elasticity and horizontal shearing strength of BLVL was discussed. The results show a rising trend for the lightness (L*) as well as red hue (a*) and yellow hue (b*) with increasing extent of removing bamboo green, The higher the extent of removing bamboo green, the less wax and SiO 2 remained on the bamboo surface, the smaller the contact angle of bamboo-bundle and the better the dimensional stability of the corresponding BLVL. As the removing extent of bamboo green increased, BLVL exhibited a slightly decreasing value of modulus of rupture, modulus of elasticity and horizontal shear strength prior to the 28 h cycling treatment, while less strength reduction was observed after the treatment. The ones without removal of bamboo green suffered most severe strength reduction. In terms of horizontal shearing strength, A, B, C, D could meet the standard requirement of GB/T 20241-2006, while A, B and C, except for D, could reach the 9 V-12H level according to Bamboo Scrimber standard.

“…Bamboo is an abundant natural resource in Asia. It has been used as non‐structural and structural material in many areas . In recent years, laminated bamboo fibrillated‐veneer lumber (LBL) has been extensively promoted and applied in China for its high strength and modulus, along with considerable bamboo resource utilization rate .…”

The veneer preprocessing densification is a vital procedure in the manufacturing process of long-span bamboo-based engineering material, Bamboo-Bundle Laminated Veneer Lumber (BLVL). The adhesive used in the preprocessing densification process was the mixture of phenol formaldehyde (PF) resin and polyvinyl acetate (PVAC) resin. The objective of this study was to investigate the effect of PF/PVAC weight ratio on the moisture absorption performance of BLVL, as well as the effect of ambient temperature on the hygroscopic swelling performance for BLVLs with a PF/PVAC ratio of 6 : 1. The results indicated that the water absorption swelling rate and weight gain rate of the BLVLs decreased as PF/ PVAC ratio increased at 63 C. The absorption behavior of BLVL was found to obey Fick's law at 63 C approximately. The higher the PF/PVAC ratio, the lower swelling parameter K SR and D values were obtained. However, PF/PVAC ratio exerted little effect upon the bending properties(modulus of rupture and elasticity) of BLVL. Temperature has a significant effect on the moisture absorption performance of BLVL (6 : 1 PF/PVAC ratio). The higher the temperature, the greater swelling and weight gain rate was obtained, as well as K SR and D values. The calculated swelling activation energies (E S ) were 25.79 and 22.45 KJ mol 21 for BLVLs with 6 : 1 PF/ PVAC ratio and the ones with neat PF resin, respectively, while the diffusion activation energies (E D ) were 10.62 and 8.47 KJ mol 21
