“…[39] A concrete beam has compression and tension zones, and reinforcements are mainly needed in the tension zones to carry the tensile stresses and prevent the structure from damage. [40,41] The bamboo reinforcements in concrete beams increase the load-bearing capacity up to an optimal value of 3 to 4% with increasing percentages of longitudinal bamboo reinforcements.…”

Summary The study investigated the feasibility of replacing the steel bars by bamboo in concrete members as alternative materials in the rural and peri‐urban areas. The present study also investigated the effects of bonds between concrete and bamboo on the strength of concrete reinforced with treated and untreated bamboo. The study further examined the effect of split bamboo and whole bamboo when used as concrete reinforcements and compare with the strength of concrete reinforced by steel bars. Laboratory tests such as pull out test, flexural test, bamboo water absorption test, bamboo tensile test, and mechanical crushing test were done for this purpose. Nonlinear finite element model using ABAQUS was used to simulate the problem and validate the laboratory results. The results indicated that the bond at the interface between concrete and bamboo greatly affected the strength of bamboo reinforced concrete. The results also revealed the potential of the treated split bamboos for use as an alternative partial replacement of steel bars in concrete reinforcement and a cost‐effective approach that can be useful in most rural and peri‐urban regions where the relatively low purchasing power of the steel bars, as well as the simple structures, are dominant.

“…However, light cement bamboo frame (or bahareque) construction is common in many areas of the world (e.g. Gonzalez and Gutierrez, 2005). Such construction embeds bamboo strips in cementitious mortar to make infill panels for framed walls.…”

Bamboo is a sustainable green material and has been gradually applied in the construction industry; however, little research on strengthening masonry structures with bamboo has been carried out. In this article, strengthening methods using bamboo were developed including bamboo grid reinforced cement mortar layer, externally bonded bamboo mats, additional confining horizontal bamboo reinforced concrete band beams, and bamboo strips placed in mortar joints. Ten masonry walls were designed including two reference walls. Experimental results showed that all the strengthening methods can improve certain aspects of the seismic performance of masonry walls. The shear strength, deformability, and energy dissipation capacity of masonry walls strengthened with bamboo grid reinforced cement mortar and externally bonded bamboo mats were the most improved. The limit states of tested walls were discussed. Strengthened masonry structures with bamboo components are promising methods and can be used especially in remote areas.

“…Light cement bamboo frame (LCBF) panels, known colloquially as bahareque construction, (e.g.,Gonzalez and Gutierrez [72]) are well established. LCBF construction is a modern technique utilising composite shear panels constituted of a wall matrix of bamboo or metal lath nailed onto a bamboo framing system, plastered with cement or lime mortar render.…”

Bamboo reinforced concrete: a critical review

et al. 2018

The use of small diameter whole-culm (bars) and/or split bamboo (a.k.a. splints or round strips) has often been proposed as an alternative to relatively expensive reinforcing steel in reinforced concrete. The motivation for such replacement is typically cost-bamboo is readily available in many tropical and sub-tropical locations, whereas steel reinforcement is relatively more expensive-and more recently, the drive to find more sustainable alternatives in the construction industry. This review addresses such 'bamboo-reinforced concrete' and assesses its structural and environmental performance as an alternative to steel reinforced concrete. A prototype three bay portal frame, that would not be uncommon in regions of the world where bambooreinforced concrete may be considered, is used to illustrate bamboo reinforced concrete design and as a basis for a life cycle assessment of the same. The authors conclude that, although bamboo is a material with extraordinary mechanical properties, its use in bamboo-reinforced concrete is an ill-considered concept, having significant durability, strength and stiffness issues, and does not meet the environmentally friendly credentials often attributed to it.
