Bamboo Infrastructure and Buildings a step towards Sustainable City and Rural Developments
Bamboo is one of the oldest traditional building materials used by mankind. They are the largest members of the
grass family and are the fastest-growing in the world. In fact, within a 24 hour period, bamboo can grow four feet. Bamboos are of notable economic and cultural significance in South Asia, Southeast Asia and East Asia, being used for building materials, as a food source, and as a versatile raw product. Bamboo has a higher compressive strength than wood, brick or concrete and a tensile strength that rivals steel.
This is a substitute building material, which is renewable, environment friendly and widely available, as the wood resources are diminishing and restrictions are imposed on felling the natural forests. Due to its rapid growth, its adaptability to most climatic conditions and due its properties, bamboo emerges as a very suitable alternative.
WHY BAMBOO IS USED AS A BUILDING MATERIAL?
Housing is a basic need for human being, and is now becoming a burden for low and medium income group. Thus,
we need cost effective housing and bamboo is the best building material, result for that as:
- It is fastest-growing renewable natural building material.
- The material is easily available & Eco friendly.
- Bamboo is a viable (if not better!) alternative for steel, concrete and masonry as an independent building
- It is cost effective and easy to work.
- It can be easily bend, give desired shape and can provide joints to suit the construction.
- Its enormous elasticity makes it a very useful building material in areas with very high risks of earthquakes.
- Local available material to some areas, which tries to carry the local tradition & vernacular Architecture of that
Advantages of Bamboo as a Building Material
The various advantages of bamboo are as mentioned below:
- Tensile strength: Bamboo has higher tensile strength than steel because its fibers run axially.
- Fire Resistance: Capability of bamboo to resist fire is very high and it can withstand temperature up to 4000 C. This is due to the presence of high value of silicate acid and water.
- Elasticity: Bamboo is widely preferred in earthquake prone regions due to its elastic features.
- Weight of bamboo: Bamboos due to their low weight are easily displaced or installed making it very easier for transportation and construction.
- Unlike other building materials like cement and asbestos, bamboo poses no danger to health.
- They are cost effective and easy to use.
- They are especially in great demand in earthquake prone areas.
