5. Abstract
Bamboo has a huge potential to be used under affordable housing. The beauty
about bamboo is that it has an inherent negative carbon foot print in its natural
round form. This ability can aid in developing a nearly zero carbon foot print
construction using round bamboo. Also, it has been observed in India that the
traditional constructions of houses are with bamboo used as a load distributor and
not as a main load bearing element. The key to achieve higher bending strength,
required for main load bearing elements, is through enhancing the second
moment of area to achieve desired bending strength. This is achieved using a new
innovative jointing technology i.e. Haritha IITD Bamcrete Technology (HIB) for
developing twin bamboo columns as main load bearing elements to develop
bamcrete columns (bamboo concrete composite columns). The present study
reports the performance of a twin bamboo column developed using HIB
technology & tested to 32 kN load under pure axial loading, with lateral restrains,
developing compressive stress of 14 MPa in bamboo

6. Introduction
• Bamboo is widely used in the construction industry for various
purposes such as scaffolding construction of bridges and structures
etc.
• Bamboo defines as a tall tropical plant with hard and hollow stems.
• Bamboo is a natural product which is widely used in the construction
of partition walls floorings and ceiling panels and for roofing.
• Bamboo is one of the fastest-growing plants in all over the world.
Bamboo is a renewable resource which can be cultivated in different
types of solid.
• Bamboo has referred mostly in the earthquake-prone regions due to
its elastic properties.
• Bamboo is widely used for the construction of partition walls and
beams which are the main structural elements of any structure.
• Bamboo is the best option for the roofing material and widely used
by the people in the construction of structures especially where
bamboo is in abundance.
• Bamboo has a natural surface which is smooth and clean and very
attractive and does not require painting. That’s why it is very cost
effective to use bamboo as a construction material.
• Bamboo is ancient construction material and widely used in different
countries for the construction because of its high compressive
strength and tensile strength.

8. METHODOLOGY
The structure we have constructed consists of 4 VERTICAL members 12
HORIZONTAL member and 8 INCLINED member as shown in the 3D model. The
dimensions for the same are explained below:-
1) 4 VERTICAL members- 110 cm(2), 50 cm(2)
2) 8 horizontal members- 105 cm (4), 35 cm(4)
In order to join these members, we have made use of keys. The keys are small rod
like structure which help in connection of membranes easily. Each and every part of
our structure has been prepared using bamboo, we have not utilized any adhesives
for the same.
The tools that we have used for the construction include :-
1) Hex saw
2) Bamboo cutter
3) Hammer
4) Drilling machine
5) Cut off saw
6) Angle grinder
These are the tools that we have utilized for constructing our model.

9. PLANNING AND DESIGN
1)Draw Rough Diagram of Product.
2) CREATE 3D MODEL

10. 3) CREATE ACTUAL PRODUCT
Steps follow by we for creating actual structure of step:
Step 1: We cut a pair of bamboo and create 4 pieces of 3ft, 12 pieces of 1 ft and 8
pieces of 1.8 ft.
Step 2: Then we perform compression test on the selected material that
Step 3: That 12 pieces given fish mouth cut on both the side.

11. Step 4: Then with the help of marker we made marking on bamboo and with the
help of drill machine we drilled on bamboo.
Step 5: Then we made key with the help of chisel to make the joint strong.
Step 6: Then the final work of assembly is done.

✓ Precautions taken by us:
1. Keep distance from electric machine
2. Carefully handle the electric machines
3. Wearing tight clothes and also tight shoes
4. Taken regular breck after some time
5. Unused material set outside of working space
6. Keep clean working space

13. Cost Analysis
Direct Cost:
1.Cost of raw materials:
Bamboo = total bamboo used x rates per m
= (15m × 2) × (5)
= Rs. 150
2.Labour cost:
Rates:
Skilled labour = Rs 400/day
Unskilled labour = Rs 200/day
Total labour cost = Rate of skilled labour x no. of working days
= Rs 400/day x 4 days
= Rs 1200
Total labour cost = Rate of unskilled labour x no. of working days
= Rs 200/day x 4 days
= Rs 800
Total Labour cost=1200+800
=Rs 2000
BUT THERE ARE NOT ANY LABOUR WORK SO,
TOTAL LABOUR COST : RS 0

14. 2. Electricity Cost :
Approximately 23 units will be consumed during production of truss. Cost of one unit is
Rs. 9
Total electricity cost = 18 units x Rs 8
= Rs. 144
Cost Analysis
Type of cost Elements Cost
Direct Material Rs 150
Labour Rs 0
Indirect Hiring of machines Rs 875
Electricity Rs 144
Total Rs 1169

15. Conclusion
Bamboo reinforced concrete column achieved desired strength. Failure occur in
compression are of similar pattern. Fissures at the edges and cracks along the length
of column. Proper workmanship and skilled supervision help in getting desire
strength. Compaction of concrete should be adequate or else honey combed
structure are created. Bamboo reinforcement should be coated with black Japan as
it has good water repellent and bond quality. Bamboo reinforcement should not be
exposed to environment as it created defects like swelling and decay. Load
displacement and stress strain curves in bamboo reinforce column show typical
pattern as in steel reinforce column. For low-cost housing projects bamboo
reinforce structure is feasible and gives desired strength. Steel formwork should be
used for good quality and for achieving desired strength
