The document discusses bamboo reinforced concrete. It describes bamboo characteristics, selection criteria, placement in concrete, and applications as an engineering material. Bamboo reinforced concrete elements discussed include beams, columns, and slabs. Advantages are low cost, eco-friendliness, and seismic resistance. The conclusion is that bamboo can compete as a sustainable building material for light, temporary structures and finishing applications.

CEMETNT PAVEMENT SLABS IN WHICH THE SLABS BEHAVE IN ELASTICALLY EVEN
UNDER LIGHT LOADS.
5. BAMBOO CAN BE USED AS AN ALTERNATIVE MATERIAL IN REINFORCEMENT OF
CONCRETE .
INTRODUCTION :
 Bamboo is characterized as a bio degradable,renewable and
an energy efficiency natural resource.
 It is an environmentally sustainable building material.
 It has been used as construction material in certain
areas for centuries.
Bamboo can be used as an alternative material in
reinforcement of concrete.

4. 1. BAM CAN PREVENT POLLUTION
BAMBOO CHARACTERISTICS:
 Bamboo is a giant grass and not a tree
 The density of fibres in cross section of a bamboo shell
varies with thickness as well as height
 Bamboo is more prone to insect attack than other trees and
plants
 Bamboo can prevent pollution

5. SELECTION OF BAMBOO :
 Use only bamboo showing a pronounced brown color. This
will ensure that the plant is at least three years old.
 Select the longest large diameter culms available.
 Avoid bamboo cut in spring or early summer.
 There are more than 1500 species of bamboo, but only
certain species can be used for the construction process.

6. Bamboo reinforcement should not be placed less than 1½
inches from the face of the concrete surface.
Reinforcement should be evenly spaced and lashed
together on short sticks placed at right angles to the main
reinforcement.
The ties can be made with vegetation strips.
Spacing of the stirrups should not exceed 6 inches.
PLACEMENT OF BAMBOO :

7. BAMBOO AS AN ENGINEERING
MATERAIL
 Durability
 Effect of water absorption
 Bonding strength

8.  DURABILITY :
 The durability varies with the type of species, age,
conservation condition , treatment and curing
 Bamboo reinforcement is more durable than steel
reinforcement
 The durability increases with the decrease in
humidity and starch content of the bamboo

9.  EFFECT OF WATER ABSORPTION
 The main shortcomings of bamboo is its property of
water absorption.
 The dimensional variation of untreated bamboo due to
water absorption can cause micro or even macro cracks
in cured concrete.
 This can be controlled by treating the bamboo.

10.  BONDING STRENGTH
 The bonding strength depends on the adhesion property
of cement and compression friction forces appearing on
the surface of the reinforcing bar.
 The below three properties influence the bonding
strength:
a) swelling of bamboo pushes the concrete away
b) creates voids in the concrete
c) leads to the cracking of concrete
 Bonding strength can be increased by 90% by treating the
bamboo.

ADVANTAGES OF RBC :
 Low cost construction.
 It is eco friendly as it absorbs NO2 in water
and CO2 in air
 Bamboo is easily accessible.
 It withstands 7.8 Richter of seismic attack

CONCLUSION :
It is a boon for light weight and temporary
buildings .
The environmental and financial comparison
demonstrates that bamboo can compete as a
building material.
Further more bamboo can play a role a finishing
material.
