A PRESENTATION ON BABOO

1. BAMBOO
PRESENTED BY- ANUJ KUMAR MAURYA

2. INTRODUCTION
• BAMBOOS ARE A DIVERSE GROUP OF EVERGREEN PERENNIAL FLOWERING
PLANTSIN THE SUBFAMILY BAMBUSOIDEAE OF THE GRASS FAMILY POACEAE.
• GIANT BAMBOOS ARE THE LARGEST MEMBERS OF THE GRASS FAMILY.
• THE ORIGIN OF THE WORD "BAMBOO" IS UNCERTAIN, BUT IT PROBABLY COMES
FROM THE DUTCH OR PORTUGUESE LANGUAGE.

3. CHARACTERIST
ICS
LIGHT WEIGHT.
FLEXIBLE.
TOUGH.
HIGH TENSILE.
CHEAP MATERIAL THAN THE OTHER BUILDING MATERIALS LIKE STEEL.
BAMBOO STRUCTURES ARE FLEXIBLE.
EARTHQUAKE RESISTANT.
LIGHT WEIGHT AND CHEAP.

4. ADVANTAGE AND
DISADVANTAGE
ADVANTAG
E
EASY TO GROW
PRIVACY SCREENING
ENVIRONMENTAL BENEFITS
PEST RESISTANCE
VERSATILITY
DISADVANTAG
E
BAMBOO IS INVASIVE
A THREAT TO BIODIVERSITY
DIFFICULT TO ERADICATE
SHRINKAGE
DURABILITY

5. FLOORING
• THE FLOOR IS RAISED ABOVE THE GROUND CREATING A STILT TYPE
OF CONSTRUCTION THAT PROVIDES A COVERED STORAGE AREA BELOW THE
FLOOR.
• THE SURFACE OF THE EARTH FLOOR CAN STABILIZE BY PAVING IT WITH
CRUDE BAMBOO BOARDS MADE BY OPENING AND FLATTENING WHOLE
CULMS.

6. TYPES OF BAMBOO USED
1.SMALL BAMBOO COLUMN
 THESE ARE DIRECTLY TIED AND NAILED TOGETHER
2.SPLIT BAMBOO COLUMN
 CULMS ARE ALONG THEIR LENGTH INTO STRIPS
3.FLATTENED BAMBOO
 HERE THE GREEN BAMBOO CULMS ARE SPLIT
BY REMOVING THE DIAPHRAGMS, THEN ROLLING
AND FLATTENING THEM.
 AS A RESULT OF THIS, THE BOARD IS LAID ACROSS
THE JOISTS AND FIXED BY NAILING OR TRYING WHICH
IS FINALLY SCREENED WITH CEMENT MORTAR AS THEY
ARE UNEVEN AND DIFFICULT TO CLEAN.

7. WALLS
• BAMBOO IS EXTENSIVELY USED IN WALLS
AND PARTITIONS WHERE
THE POSTS AND BEAMS ARE THE
STRUCTURAL FRAMEWORKS, THAT CARRY
THE SELF-WEIGHT OF BUILDING
AND MOVING LOADS.
• AN INFILL BETWEEN FRAMING MEMBERS NOT
ONLY COMPLETES THE WALL BUT
ALSO SERVES THE PURPOSE
OF PROTECTING AGAINST RAIN, WIND, AND
ANIMALS, TO OFFER PRIVACY AND STABILITY
OF OVERALL
STRUCTURE TO COMPETE AGAINST HORIZONTAL

8. ROOFING
• THE BAMBOO STRUCTURE OF A ROOF COMPRISES PURLINS, RAFTERS & TRUSSES BECAUSE IT
IS STRONG, RESILIENT & LIGHT–WEIGHTED.
• BAMBOO PURLIN AND BEAMS SUPPORTED ON PERIMETER POSTS ARE THE SIMPLEST FORMS.
• THE FIRST LAYER OF HALVED CULMS IS LAID ON A CONVEX SIDE DOWN, EDGE-TO–
EDGE, SPANNING FROM THE RIDGE TO EAVES.
• HE SECOND LAYER, OPPOSITE TO THAT IS LAID CONVEX SIDE UP, TO COVER THE JOINTS.
• CORRUGATED SHEETS MADE OF BAMBOO HAVE BEEN USED AS A ROOF COVERING WHERE,
BAMBOOS ARE GENERALLY DIPPED IN RESIN, DRIED, AND HEATED UNDER PRESSURE IN A
PLATEN TO ENHANCE THE PROPERTY OF BAMBOO, FOR INSTANCE, STRONG, RELIABLE,
AND LIGHTWEIGHT SHEETS.
• A LAYER OF BITUMEN SANDWICHED BETWEEN TWO MATS OF BAMBOO FORMING A SEMI-
RIGID PANEL, FIXED AT AN INTERVAL OF 200-250MM, FOLLOWED BY FINISHING OF
BITUMINOUS OR RUBBERIZED WEATHERPROOF COATING.

9. TRADITIONAL PRESERVATION OF BAMBOO
• PRESERVATION OF BAMBOO USING TRADITIONAL METHODS SUCH AS SOAKING
BAMBOO IN BOTH RUNNING AND STILL WATER HAS BEEN CARRIED OUT BY RURAL
COMMUNITIES.
• THIS METHOD AIMS TO REDUCE STARCH IN BAMBOO, AND IT IS APPLIED TO
BAMBOO, WHICH WILL BE USED AS BUILDING MATERIALS.
• SOAKING BAMBOO IN WATER IS NOT RECOMMENDED TO EXCEED 30 DAYS.
• AFTER REDUCING STARCH, THE BAMBOO IS LESS LIKELY TO BE ATTACKED BY
POWDER BEETLES, DAMAGING THE BAMBOO.
• THE DECREASE IN STARCH CONTENT CAN ALSO INCREASE THE STRENGTH OF THE
BAMBOO.
• FURTHERMORE, THIS PRESERVATION IS CONSIDERED COMPLETE WHEN THE COLOR
OF THE BAMBOO IS PALE (NOT YELLOW, GREEN, OR BLACK), AND IT HAS A

10. CHEMICAL PRESERVATION OF BAMBOO
• IT IS A SIMPLE CHEMICAL METHOD THAT UTILIZES THE FORCE OF GRAVITY.
• CHEMICAL METHODS ARE RELATIVELY EXPENSIVE, BUT THEY RESULT IN BETTER
SURFACE PROTECTION.
• CURRENTLY, THE USE OF CHEMICAL PRESERVATIVES TO INCREASE THE
RESISTANCE OF BAMBOO TO TERMITE ATTACKS HAS OFTEN BEEN DONE.
• THIS METHOD'S SUCCESS DEPENDS ON THE ACCURACY OF THE CONCENTRATION
OF THE PRESERVATIVE SOLUTION GIVEN.
• SOME OF THE KNOWN CHEMICAL METHODS OF BAMBOO PRESERVATION ARE THE
BUTT TREATMENT METHOD, THE OPEN TANK METHOD, THE BOUCHERIE METHOD,
AND FUMIGATION (WITH METHYLBROMIDE COMPOUNDS).
• CHEMICAL METHODS ON A LARGE SCALE ARE WIDELY USED IN INDIA, TAIWAN,
AND JAPAN.
