Structural Properties of Bamboo Reinforced Concrete

Bamboo based on its availability has been widely and its mechanical properties is widely used as reinforcement in concrete structures. As it proves to be a sustainable solution for steel reinforcement, there is still some key questions regarding its structural capacity and future sustainability issues.

All major studies performed was generally based on bamboo bars that are whole culms of small diameter or semi-round strips called as the splints. Lets discuss some of the important properties one by one.

Structural Properties of Bamboo Reinforced Concrete

  1. As per a studied conducted ( Agarwal et.al) it was shown that the bond between the bamboo reinforcement and concrete can be improved by using epoxy-based adhesives. As per the studies, average bond stress of plain bamboo splints as recorded from pull-out tests was in the order of 0.13 MPa. It was studied that bamboo reinforcing ratio of 8% is is necessary to obtain similar behavior of flexural strength of steel reinforced concrete. It is desirable to obtain a reinforcing ratio of 0.89 % and a modular ratio of Esteel/Ebamboo = 8.3
  2. The allowable stress is limited in bamboo reinforced concrete as it is brittle in nature compared to steel which is ductile.
  3. The characteristic values of longitudinal tensile modulus and strength is less that 10% for bamboo reinforced concrete as per the study conducted as per Kaminski et al.
  4. The coefficient of thermal expansion of bamboo is different from that of steel and concrete. It is greater in magnitude in the traverse direction compared to the longitudinal direction which influences the composite bond behaviour.
  5. Bamboo is dimensionally unstable compared to steel and it demands some form of treatment to resist moisture transmission. Due to its anisotropic properties, the dimensional stability is not uniforms along longitudinal and traverse direction.
