“…Gavrilovic et al (2012) stated that the CA increase as fluid viscosity increase. A comparison of contact angle was also made between parts and surface in the culm (Chaowana et al 2015), the outer surface (bamboo skin) and inside surface (bamboo pith) , height levels and surface (Marasigan et al 2020). Those studies reported that the CA of the inner surface was lower than that of the outer surface, the CA of the bottom culm lower than the top culm, and the CA of nodes less than the internodes.…”

Bamboo-based composite has been used widely for building components and furniture. Oriented flattened bamboo board (OFBB) is a composite board consisting of oriented structure sheets of flattening bamboo. This study aimed to analyze the physical and mechanical properties of the OFBB from ater (Gigantochloa atter) and betung (Dendrocalamus asper) bamboo. A three-layer flattened bamboo board using the isocyanate resin with a density target of 0.6 g/cm3 was applied. The characteristics of raw bamboo, the contact angle of OFBB, and board properties of density, moisture content, thickness swelling, and water absorption, as well as bending, internal bonding (IB), and compressive strength properties were determined to evaluate the quality of the OFBB. Based on the findings, the thin wall thickness of ater bamboo enhanced the physical and mechanical properties of the OFBB compared to the higher wall thickness of betung bamboo. Therefore, further development in bamboo composite products with those anatomical properties seems promising. The dimensional stability and bending properties of OFBB from ater bamboo met the quality of first grade of the Canadian Standard for OSB and waferboard, except for the IB strength.

“…The linear density (T) is determined for each BV fiber of Figure 2 by weighing the mass (m) using an electronic balance (accuracy 0.01 mg) and by measuring the length (l) with a digital calliper (accuracy 0.001 mm) in accordance with the standard NF G 07-007. 24 The linear density was measured in each of the sampling 22,23 zones and was calculated using equation (1) which was applied for Mesocarp oil palm and pineapple leaves fibers. 25,26…”

In this study on characterization of bambusa vulgaris fibers from Cameroon (BV), we evaluated the linear density as well as the moisture uptake. With the help of SEM, the cross-sections were observed to be circular shapes; they increase from outside to inside in any transverse position along the stem. Also, the degradation temperature of BV was investigated with the aid of TGA and the result showed that the degradation temperature of BV fibers is between 366 °C and 380 °C. In addition, their Young's moduli in dynamic tensile test was determined and it was noticed that the Young moduli increase from inside to outside. The bending tests of BV fibers were carried out and enable the various parameters in zone 3/3. Finally, the creep behavior of BV fibers was studied and it was revealed that the 4-element Burger model describes very well this phenomenon and could help in well predicting fatigue behaviour of BV fibers reinforced composites.

“…Yang et al [28] proved that rosin impregnation improved the dimensional stability and hydrophobicity of bamboo. Marasigan et al [29] studied the effect of thermal treatment on the wettability of giant bamboo (Dendrocalamus asper) and Kawayan Tinik (Bambusa blumeana) in the Philippines, and found that thermal treatment changed the color of both bamboo species, the density decreased, and improved the wettability.…”

Bamboo is the building material of the past and future. It offers numerous properties that make it versatile for various applications, including construction. Its impressive strength-to-weight ratio enables it to bear substantial loads and stresses, while its good elasticity allows efficient energy absorption. However, its mechanical properties can vary based on factors such as species, age, locations, methods, and treatment. Treating bamboo is essential to enhance its properties and durability. The literature provides various natural and chemical treatments that enhance some of the properties but also reported drawbacks regarding higher temperature, content, and duration. This paper reviewed 57 articles from the Scopus database, specifically focusing on article–document-type publications from the years 2003 to 2023. Additional references were also incorporated to address concerns in properties, treatment, and standards to provide systematic understanding. With extensive assessment of the articles, the following gaps and concerns were observed, and recommendations for further study and assessment were made: the bamboo’s properties, the development of centralized guidelines and procedures for the preparation and processing; the exploration of alternative materials to reinforce bamboo without compromising its ductility; and the development of joint connections, and testing of mechanical properties considering seismic, wind and vibration. For treatment methods, the standardization of procedures using natural, chemical, or a combination. Lastly, for bamboo codes and standards, the assessment of existing codes and standards for testing the mechanical properties of bamboo, highlighting the potential limitations and areas, uniformity, and differences with all existing similar standards. By filling these gaps, it can support the reliability and robustness of bamboo as a sustainable material, fostering its promotion and adoption in the construction industry.
