= Bamboo Reinforced Concrete
Concrete is usually reinforced by steel or bricks
What are the advantages of using bamboo instead of steel or
bricks?Steel VS BambooSteel is a high tech materialHigh amount of
energy is needed for productionEnergy for furnace, forming, etc.Ore
mining is necessarySteelmaking processes produce CO2High cost
processBamboo...Natural resourceQuickly Renewable LOW
COSTEnvironment friendly - recyclable
Steel VS Bamboo...Steel (A36 steel)Yield Strength = 250
MPaTensile Strength = 400 MPaDensity = 7.8 gr/cm3Elastic Modulus =
210 GPaBamboo (Depending on species and part of the culm)Tensile
Strength = 100-150 MPa Elastic Modulus = 600-900 MPaDensity = 1.25

Disadvantages of Using BambooWater absorption and weak interface
with cement/concreteProperties vary depending on age, species, and
part of the culmSolution?Solution?Water absorption water resistant
