“…While there is growing interest in the use of wood fibers to enhance the mechanical behavior and fracture toughness of concrete [23][24][25], there has so far been relatively little investigation of the use of bamboo fibers for this purpose. Only a few studies [26][27][28][29][30] investigated the performance of bamboo fiber-reinforced concrete and mortar mixtures through a series of mechanical tests. The bamboo fibers in those studies were obtained from bamboo forests and were subsequently processed as fibers for concrete mixtures.…”

In this study, a sustainable mortar mixture is developed using renewable by-products for the enhancement of mechanical properties and fracture behavior. A high-volume of fly ash—a by-product of coal combustion—is used to replace Portland cement while waste by-products from the production of engineered bamboo composite materials are used to obtain bamboo fibers and to improve the fracture toughness of the mixture. The bamboo process waste was ground and size-fractioned by sieving. Several mixes containing different amounts of fibers were prepared for mechanical and fracture toughness assessment, evaluated via bending tests. The addition of bamboo fibers showed insignificant losses of strength, resulting in mixtures with compressive strengths of 55 MPa and above. The bamboo fibers were able to control crack propagation and showed improved crack-bridging effects with higher fiber volumes, resulting in a strain-softening behavior and mixture with higher toughness. The results of this study show that the developed bamboo fiber-reinforced mortar mixture is a promising sustainable and affordable construction material with enhanced mechanical properties and fracture toughness with the potential to be used in different structural applications, especially in developing countries.

“…Bamboo fi bers are usually obtained by crushing and grinding the bamboo culms into small fi bers and then removing the moisture content by drying [78]. The length of bamboo fi bers used in concrete varies from 10 mm to 67.5 mm [79][80][81]. Bamboo fi bers do not improve the compressive strength of concrete.…”

Bamboo is a naturally available, fast growing and renewable resource. Bamboo plants are found all over the world in tropical and non-tropical regions. Asia pacific region is specifically rich in bamboo biodiversity. Due to high energy demand of existing construction materials and scarcity of other naturally available materials like wood, bamboo is a good alternative for construction. This paper reviews the mechanical properties and use of bamboo in construction. The tensile strength of different bamboo species varies in the range 70-210 MPa, compressive strength 20-65 MPa, elastic modulus 2500-17500 MPa, and modulus of rupture 50-200 MPa. Bamboo is a versatile material and can be used in construction in various ways. Bamboo can be engineered to specific need in construction such as laminated and scrimber bamboo. Engineered bamboo are used for various housing purposes such as roofing and flooring. Bamboo culms are often used directly without any alteration as structural members such as beams and columns. Bamboo can also be used as reinforcement in concrete as a replacement to steel. The shear and flexural behavior of bamboo reinforced concrete (BRC) beams is significantly better than plain concrete beams. Bamboo fibers reinforced concrete (BFRC) is a good alternative to existing synthetic fibers reinforced concrete such as glass and steel fibers. Development of standardized testing procedures and structural specifications utilizing existing and future research findings will pave the way towards an extensive use of bamboo in construction industry.

“…be recommended. In addition, adding an appropriate amount of bamboo fiber to concrete, like other chopped fibers, could improve the tensile properties of concrete, control the development of early cracks, and significantly improve ductility and toughness [12][13][14][15]. Therefore, this paper took BFRP bar concrete beams reinforced with bamboo fiber and steel wire mesh as the research object, and conducted flexural tests and numerical simulation of the experimental beams by changing the length of the bamboo fiber and the layout of the steel wire mesh.…”

To explore the effect of adding bamboo fiber and steel wire mesh to BFRP bar-reinforced concrete beams on their flexural performance, we designed and fabricated six test beams with different parameters. Through flexural tests and numerical simulations, the effects of bamboo fiber length and steel wire mesh layout on the crack resistance, deformation capacity, and flexural ultimate bearing capacity of BFRP bar concrete beams were assessed. The feasibility of the simulation and the calculation method of flexural capacity of such specimens were considered. The research results showed that the addition of bamboo fiber can increase the cracking load and global stiffness and reduce the deformation of the test beam, but this had little effect on the ultimate flexural bearing capacity of the test beam. The cracking load, global stiffness, and ultimate flexural bearing capacity of the test beams were improved by the addition of steel wire mesh, and the stiffness and ultimate flexural bearing capacity of the test specimens with steel wire mesh in the whole beam were improved. Although the composite effect of bamboo fiber and steel wire mesh showed some improvement in these indicators, the improvement effect was not ideal.
