“…Bamboo culm is also utilized to produce composite materials or used as reinforcement in which the application could be optimized. Sayed et al [87] studied bamboo sticks and used it as reinforcement for concrete, Fabricating a concrete tube with bamboo sticks. Using bamboo sticks as reinforcement improves the compressive strength of concrete.…”

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.

“…The civil construction industry is booming with the expansion of the global economy since the early 21st century. However, environmental problems and the unsustainable development of resources brought about by the rapid development of the industrial era have become increasingly significant [1][2][3]. In the future, the development mode of using natural river sand and fresh water as the main raw materials for construction will be changed, so it has become particularly important to find construction resources that can replace these materials [4].…”

A total of 66 sets of pullout specimens were prepared to investigate the bonding properties of basalt fiber-reinforced polymer reinforcement (hereinafter referred to as BFRP) with seawater sand concrete (hereinafter referred to as SSC). The volume dosages of mono-doped glass fibers and mono-doped polypropylene fibers were 0.1%, 0.2%, and 0.3%; the total volume dosage was set to be constant at 0.3%; and the doping ratios of the hybrid fibers were 1:2, 1:1, and 2:1. The effect on the bonding performance of BFRP reinforcement with SSC was studied on the condition of the diameter D of the BFRP reinforcement being 12 mm; the bond length of SSC being 3D, 5D, and 7D; and the surface characteristics of the reinforcement being sandblasted and threaded. The research showed that due to internal cracks in the matrix, salt crystals in the pores, chloride salts with high brittleness and expansion, as well as sulfate corrosion products such as “Frederick salts” in SSC, the concrete became brittle, resulting in more brittle splitting failures during the pullout test. Doped fibers can increase the ductility effect of concrete, but the bonding effect between the threaded fiber reinforcement and the SSC was not as good as that of the sandblasting group. When the bond length was 5D, the bonding effect between the BFRP reinforcement and SSC was the best, and the bonding performance of the experimental group with doped fibers was better than that of the threaded group. Finally, by combining the ascending segment of the Malvar model with the descending segment of the improved BPE model, a constitutive relationship model suitable for the bond–slip curve between BFRP reinforcement and SSC was fitted, which laid a theoretical foundation for future research on SSC.

“…To improve the mechanical properties of bamboo structures, researchers have started to combine bamboo with other materials, such as steel and concrete to form steelbamboo composite structures [9][10][11][12], bamboo tube-confined concrete columns [13][14], and bamboo-reinforced concrete structures [15][16][17]. Moreover, bamboo fibers or rods have been mixed with concrete to improve its fracture toughness [18][19][20][21][22].…”

To alleviate the serious loss of gravel resources and improve the sustainability of concrete materials, this study innovatively proposes the development of a new type of bamboo aggregate from green and renewable Phyllostachys edulis (Moso) bamboo to replace traditional gravel aggregates. To realize the direct application of bamboo aggregates, this study proposes the use of epoxy mortar (EM) and polyurethane (PE) adhesives to modify the bamboo surface. Compared to unmodified and PE-modified bamboo, EM-modified bamboo showed significantly improved physical and mechanical properties. Durability tests revealed that the modified bamboo, especially EM-modified bamboo, was less affected by acidic and alkaline corrosion than the unmodified bamboo and the mass loss rate was almost zero. In the early stages of alkaline corrosion, the strength of the bamboo increased, and then began to decrease after 28 d. The removal of the outer green bamboo significantly improved the adhesion of the adhesive to the bamboo surface, as confirmed by pull-out tests. A sufficient bonding area between the EM-modified bamboo and the cement matrix remained after compression damage, whereas obvious debonding behavior between the cement matrix and unmodified and PE-modified bamboo was observed. In summary, EM modification significantly improved the comprehensive performance of bamboo aggregates. This study is expected to help improve the utilization rate of bamboo, promote bamboo concrete, reduce carbon emissions, and develop sustainable materials.
