“…Comparison of the low-technology approach (manual methods with minimal mechanical processing) and the high-technology approach (substantial processing and use of heat for lamination) are of particular interest. Studies have shown increased mechanical processing requires additional energy inputs (Xiao et al, 2013) and losses in material as illustrated in the comparison of bamboo scrimber and laminated bamboo in Figure 3. Mahdavi et al (2012) studied a low-cost method for laminated bamboo using Phyllostachys pubescens Mazel ex J. Houz.…”

“…Pereira and Faria (2009) investigated glue laminated bamboo made from Dendrocalamus giganteus, a species commonly found in Brazil, using Brazilian standards for wood. An increasing number of recent publications utilise ASTM (2009) D143: Standard test methods for small clear specimens of timber (Correal et al, 2010;Mahdavi et al, 2012;Sinha et al, 2014;Xiao et al, 2013). Testing and development of engineered bamboo through timber standards will aid in the development and application of this novel material.…”

Bamboo is a rapidly renewable material that is available globally and comparable in strength to modern structural materials. The widespread use of bamboo in construction is limited by the inherent variability in its geometric and mechanical properties, and the lack of standardisation. Engineered bamboo aims to reduce the variability of the natural material and is processed and manufactured into laminated composites. Although the composites have mechanical properties similar to other structural materials, the products are currently limited to architectural applications. A field of research on engineering bamboo is emerging with the aim to demonstrate and expand its use to structural applications. To summarise the state of the art, a review of published research is presented with the focus on two types of engineered bamboo: bamboo scrimber and laminated bamboo. The materials are compared with structural timber and laminated veneer lumber to demonstrate the potential applications and practical use.

Changes in the cellulose crystallinity of moso bamboo cell walls during the growth process by X-ray diffraction techniques

et al. 2015

We investigated the changes in cellulose crystallinity in the cell walls of moso bamboo (Phyllostachys pubescens Mazel) during the growth process. Changes in crystallinity in bamboo cell walls were traced along the longitudinal and radial directions using flat-sawn specimens obtained from each internode using X-ray diffraction measurements. Cellulose crystallinity in cell walls in the same culm was higher around the base of the bamboo culms in less than 10 days after the emergence of bamboo shoots, while the upper internodes remained lower in crystallinity. Thereafter, crystallinity in the upper internodes of bamboo culms became higher. This suggests that cellulose crystallinity within bamboo cell walls has gradually increased from the base to the top with the elongation of the internode during the growth process of bamboo shoots. In addition, cellulose crystallinity in cell walls increased particularly in the outer part of the bamboo culms in all internodes. Moreover, increases of crystallinity occurred after elongation growth of internodes. It is considered that increases in crystallinity in the outer portion of each internode are one of the countermeasures of bamboo culms against increased bending moment due to the elongation growth.

“…Thus, the design values (f3d) of bamboo scrimber using the Chinese allowable stress design method, and (f4d) using ASTM D2915 (2003) can be calculated according to Eqs. 10 and 11 (Xiao et al 2012),…”

The objective of this study was to provide fundamental parameters for the utilization of bamboo scrimber in the building structure field as a green building material. Both static tensile and compressive tests were conducted on bamboo scrimber, with 180 specimens for compressive tests and 173 specimens for tensile tests. The normal and lognormal distributions were selected to fit the experimental data. The design values were calculated according to the Chinese allowable stress design method and ASTM D2915 (2003). The results showed that both tensile strength (UTS) and compressive strength (CS) parallel to the fiber of bamboo scrimber were significantly higher than those of wood and other bamboobased composite materials. Kolmogorov-Smirnov and chi-squared test results indicated that a lognormal distribution was a good fit for the UTS and CS except for the fitting result of UTS by the chi-squared test. The calculated design values of UTS and CS using ASTM D2915 (2003) were higher compared with those found using the Chinese allowable stress design method.
