“…Further investigation showed that bamboo RC beams had 134.65% of the load-carrying capacity of the unreinforced beams at 28-day. The load capacity of mild steel RC beams was 1.5 times that of its equivalent bamboo RC beams (Akeju and Falade [35]). …”

This study comparatively evaluated the flexural performance and deformation characteristics of concrete elements reinforced with bamboo (Bambusa vulgaris), rattan (Calamuc deerratus) and the twisted steel rebars. The yield strength (YS), ultimate tensile strength (UTS) and the elongation of 50 specimens of the three materials were determined using a universal testing machine. Three beams of concrete strength 20 N/mm 2 at age 28 days were separately reinforced with bamboo, rattan and steel bars of same percentage, while the stirrups were essentially mild steel bars. The beams were subjected to centre-point flexural loading according to BS 1881 to evaluate the flexural behaviour. The YS of bamboo and rattan bars were 13% and 45% of that of steel respectively, while their UTS were 16% and 62% of that of steel in the same order. The elongation of bamboo, rattan and steel were 7.42%, 10% and 14.7% respectively. The natural rebars were less than the 12% minimum requirement of BS 4449. The load-deflection plots of bamboo and steel RC beams were quadratic, while rattan RC beams had curvilinear trend. The stiffness of bamboo RC beams (BB) and rattan RC beams (RB) were 32% and 13.5% of the stiffness of steel RC beams (SB). The post-first crack residual flexural strength was 41% for BB and SB, while RB was 25%. Moreover, the moment capacities of BB and RB corresponded to 51% and 21% respectively of the capacity of steel RC beams. The remarkable gap between the flexural capacities of the natural rebars and that of steel can be traced not only to the tensile strength but also the weak bonding at the bar-concrete interface. It can be concluded that the bamboo bars are suitable rebars for non-load bearing and lightweight RC flexural structures, while more pre-strengthening treatment is required more importantly for rattan for improved interfacial bonding and load-carrying capacity. * Corresponding author.A.

Besides being chief construction ingredients, concrete and steel produce a high amount of CO2, and high energy consumption promotes global warming. To evade this problem, green and low energy consuming alternative is required. Rapid growing time with the least period to attend optimum strength made bamboo a new immerging mainstream constituent in construction. Bamboo, as one of the probable alternate structural materials, not only promises a sustainable and sturdy option but also reduces the environmental carbon footprint. In this research, article authors replaced steel reinforcement in concrete with bamboo. To establish bamboo as a construction material, a concrete beam of 200 mm × 500 mm is made in which bamboo bars of diameter 20 mm are used with a variation of 1 to 4% of the reinforcement area. Various tests were performed to provide the feasibility of bamboo as construction materials after 28 days of curing, in which test results were found promising. The impact test shows only 25% of wear and tear. Also, bamboo reinforced concrete (BRC) without changing cross sections provided 50% axial compressive strength compared to steel reinforced concrete (SRC). However, in the tensile test, BRC outperformed SRC by providing 50% more resistance against tensile load. Authors also performed rate analysis between SRC and BRC to find that it almost reduces 18% of the cost at a small scale. Hence here, comparative research is provided, and the authors believe that it would pave the road on which forthcoming researchers will walk to reach the destination of finding an alternate, sustainable, and green construction material in the form of bamboo.

“…With research findings on the suitability of bamboo as a building material for use in low-cost domestic houses, the probability of average Nigerians hoping to have their houses has increased. Akeju & Falade [4] submitted that bamboo is cheaper, locally sourced, and a better substitute to steel reinforcement in columns and beams in residential houses because it has relative advantages over steel reinforcement. It does not suffer corrosion; it contains high fibre content and high water absorption capacity.…”
