Abstract :
The escalating carbon footprint of conventional steel reinforcement and the growing demand for low-cost, locally sourced construction materials have renewed research interest in natural fibre-based reinforcement systems. Bamboo, owing to its rapid renewability, high strength-to-weight ratio, and carbon-negative growth cycle, has emerged as a promising alternative to steel in low-rise and rural reinforced concrete construction. However, the practical adoption of BambooReinforced Concrete (BRC) is constrained by an inherently weak and variable bond at the bamboo-concrete interface, driven primarily by the hygroscopic swelling and shrinkage behaviour of bamboo culms. This paper synthesises the bond mechanisms, anchorage strategies, and limit-state design framework applicable to BRC members. The relative contributions of chemical adhesion, surface friction, and mechanical interlock (particularly at bamboo nodes) to the overall bond-slip response are examined, alongside surface treatment strategies — sealing, roughening, and mechanical anchorage — that mitigate moisture-induced debonding. Experimental methods for bond characterisation, namely the direct pull-out test and the beam-end test, are reviewed together with representative bond-slip curves. A design methodology grounded in Limit State Design (LSD) principles is presented, incorporating material safety factors, development length calculations, flexural and shear design equations, and serviceability checks for deflection and crack width. A cost-benefit comparison indicates that treated bamboo reinforcement can reduce reinforcement costs by up to 50% relative to thermo-mechanically treated (TMT) steel in rural housing applications. The paper concludes that, while BRC offers substantial economic and environmental advantages, its structural application must be governed by conservative material safety factors, adequate concrete cover, and rigorous serviceability checks to account for bamboo's biological variability, moisture sensitivity, and long-term creep behaviour.
