Introduction
Concrete is a widely used construction material for its various advantages such as low cost, availability, fire resistance etc.
It cannot be used alone everywhere because of its low tensile strength. So, generally steel is used to reinforce the concrete. Though steel has a high tensile strength to complement the low tensile strength of concrete, use of steel should be limited since it is very costly and also so much energy consuming in manufacturing process.
Steel, cement, synthetic polymers and metal alloys used for construction activities are energy intensive as well as cause environmental pollution during their entire life cycle.
To overcome these problems bamboo is used as reinforcing bar in concrete.
Bamboo
Bamboo
- composite material with long and parallel cellulose fibers in its structure.
- exhibits good flexibility and toughness characteristics.
- bamboo can bend as much as touching the ground without breaking.
On the environment side, the bamboo is a harmless plant at pollution because it assimilates a lot of nitrogen and other function is to decrease the carbon dioxide in the air.
Modulus of Elasticity
Two types of specimens are used
- centre node
- nodes at 1/4th of length from each end.
central nodes stress are greater.
the nodes can resists the deflection of bamboo.
Water absorption test
“ALGICOAT RC-104” is used as a water proofing agent.
The water absorption capacity of bamboo increases with increase in nodes this may be due to presence of powder like substance at nodes.
There is no large amount of swelling in bamboo.
CONCLUSION
Based on the literature available, it was found that the research work in using bamboo as reinforcement in concrete is vast. However for smaller applications such as house hold articles using cement and bamboo reinforcement the number of publications available are scarce.
In this project an attempt is planned to be made for making light weight concrete stools for school furniture purposes in the place of wooden furniture.
