Bamboo as a buil ding material

  1. 1. INTRO… • Bamboo is a woody grass. It is the fastest-growing woody plant • Some species of bamboo grow so fast you can almost see them growing. • They are capable of growing 60 cm or more per day. • However, the growth rate is dependent on local soil and climatic conditions.
  2. 2. ADVANTAGES…  Bamboo is an extremely strong natural fibre.  It is highly flexible.  Low-cost and environment friendly.  Light weight compared to steel.  Shock absorbing and thus earthquake resistant.  Bamboo can prevent pollution by absorbing large amounts of nitrogen from waste water.  And also reducing the amount of carbon dioxide in the air.
  3. 3. USE OF BAMBOO IN CONSTRUCTION… • Scaffolding • Reinforcement • Roofing • Walling • Flooring • Doors & Windows • Decoration
  4. 4. BAMBOO AS A CONSTRUCTION MATERIAL… In ROOFS 1. Bamboo trusses 2. Bamboo tile roofing 3. Thatch roofing
  5. 5. BAMBOO AS A CONSTRUCTION MATERIAL… In Bamboo walling/ceiling 1. Bajareque wall: This wall-building technique is very well- known in Latin America. Bamboo strips are tied on either side of timber and then intermediate space is filled with mortar. 2. Bamboo board wall: This is a common method of construction in Indonesia.
  6. 6. BAMBOO WALLS WOVEN BAMBOO WALL VERTICAL HALVED COULMS BAJAREQUE WHOLE BAMBOO COULMS WATTLE AND DAUB
  7. 7. BAMBOO AS A CONSTRUCTION MATERIAL… In Bamboo flooring Bamboo can be used as flooring material due to its better wear and tear resistance and its resilience properties.
  8. 8. Modern construction: apartment unit utilizing bamboo flooring
  9. 9. In REED BOARDS Reed boards are made by flat pressing the reed at high temperatures. These reed boards are used in elements like flooring, walls, ceiling and roofing. They can also be used for partitions, doors, windows etc. In SCAFFOLDING Bamboo poles lashed together have been used as scaffolding in high rise structures due to their strength and resilience. The timber planks can be replaced with bamboo culms and these can be lashed to the vertical culms. The working platforms for masons can also be built of bamboo
  10. 10. BAMBOO FOUNDATIONS… COMPOSITE BAMBOO-CONCRETE FOUNDATIONS Single Post Footing Strip Footing
  11. 11. BAMBOO FOUNDATIONS… BAMBOO PILES • Bamboo compacts soft soil, thus increasing the bearing capacity of soil. • The friction provided by the construction-grade bamboo increases its load-bearing capacity. • Treated split bamboo piles 8m long and 80 to 90mm in diameter were filled with coconut coir strands wrapped with jute.
  12. 12. BAMBOO FOUNDATIONS… BAMBOO COLUMNS AND BEAMS Bamboo Reinforced Column Bamboo Beams
  13. 13. COMPARATIVE ANALYSIS…
