INTRODUCTION
Brick is the most widely used construction material.
The increasing demand for the construction materials lead to
exploitation of the natural resources in large extent.
Utilisation of industrial by-products for making construction
materials has gained significant attention across the world.
This project investigated the use of recycle paper mill waste
(RPMW) from Punalur Paper Mills as a raw material for
manufacture of bricks.
3
With 85% average efficiency of RPM, around 5% (by weight) of total
pulp and paper mill production is generated as RPMW annual.
As a by-product, the RPMW is usually land filled, incinerated etc.
Bricks using different RPMW-cement combination and RPMW-laterite
combination are made and their properties are evaluated.
Variation of compressive strength with variation of particle size of
RPMW is studied.
4
NEED OF STUDY
Shortfall of conventional building construction material can be reduced
by utilizing industrial wastes.
Reduction of natural recourses as well as energy.
Better way of managing industrial wastes.
5
OBJECTIVE OF THE STUDY
To compare strength characteristics of RPMW-cement bricks and
RPMW-laterite bricks with conventional clay bricks.
To compare the strength of RPMW-cement bricks by varying the
particle size of the RPMW.

SUMMARY
MATERIALS
1. RECYCLE PAPER MILL
WASTE (RPMW)
Recycle paper mill waste (RPMW)
has been obtained from Punalur
Paper Mill. This is a type of
organic material.
11
Punalur Paper Mill
Recycle Paper Mill Waste (RPMW)
Recycle Paper Mills use recycled waste paper
along with virgin pulp to produce mainly packing
paper.
The pulp is made into paper by machines.
Long length fibres go into the paper sheet on the
machine while short length fibres pass through the
machine belt and are separated at the end filter from
the waste water.
This constitutes the Recycle Paper Mills waste .

CHEMICAL COMPOSITION OF RPMW
The chemical analysis of RPMW done by using Energy Dispersive X-
ray Fluorescence Spectrometer (XRF).
The XRF test was conducted in CSIR, Trivandrum.
RPMW mainly contains Si (20%) and Ca (28%) depicting the XRF scan
data.
The silica content in RPMW mainly gives the cementitious property.
Slight amount of metals present.

2. CEMENT
• A cement is a binder, a substance used in construction that
sets, hardens and adheres to other materials, binding them
together.
• Ordinary Portland cement of 53 grade was used for the
project.
16
3. LATERITE
Laterite is a soil and rock type rich in iron and aluminium.
Nearly all laterites are of rusty-red coloration, because of high
iron oxide content.
Locally available laterite from our college was used for the
project.
Laterite was ground and particles passing through 300 µ was
used.

until it is free from moisture. The dried clay is crushed and sieved
through 300 micron sieve and the laterite passed through the sieve
is collected. The collected laterite is weigh batched according to the
proportions required.
RPMW – The grinded RPMW is sieved through 2.36mm sieve.
RPMW passes through the sieve weigh batched and used in the
required proportion

9. Placing of mix
After obtaining a uniform paste, the mix is placed into the mould
and proper compaction is given to the mix in order to avoid
formation of air voids.
Now level the surface with a trowel and remove the excess paste
using trowel. The mould is kept as such for 2 minutes without any
disturbance
Then removes the mould carefully.

10. Drying of brick
Place fresh brick in shaded area to protect it from direct sunlight as
exposure to direct sunlight can accelerate crack formation.
Place the fresh brick in shade for 3 days.
After drying in shaded area the brick is placed for sun drying for
next 25 days.

EFFLORESCENCE IS 3495 (Part 3):1992
The efflorescence test is carried according to IS 3495 (Part 3):1992.
The efflorescence is defined as the crystalline salts deposits on the
surface of bricks.
The liability to efflorescence shall be reported as ‘nil’, slight,
moderate, heavy or serious.
‘Nil’ efflorescence is present on any proportion of the brick.
40
HARDNESS TEST IS 3495 (Part 4):1992
Hardness of brick is the resistance to scratching or cutting.
In this test, a scratch is made on the brick surface by finger nail.
Slight impression is left on the brick surface
41
SOUNDNESS TEST
Two bricks are taken, one in each hand, and they are struck with
each other lightly.
A brick of good quality should not break and a clear ringing sound
should be produced.

test successfully.

WATER ABSORPTION
Water absorption is a major
factor which determines the
strength and durability of
bricks.
The void fraction imparts water
absorption property to bricks.
Because of the fibrous nature
the RPMW has high water
retention capacity

The water absorption of RPMW-cement brick is increasing with
increase in percentage of RPMW.
Proportion 80:20 is found to have lesser water absorption.
On increasing the RPMW content by 5%, water absorption was
found to be increased on an average of 2%.
High water absorption can be reduced by applying water proof
coating over the brick surface without compromising other
physical and mechanical properties of brick material.

The RPMW-laterite bricks tested were sound and has passed
soundness test successfully.
Different type of bricks like conventional clay brick, cement-
RPMW brick, cement-laterite bricks were compared in their
compressive strength.
Compressive strength of conventional clay brick is
comparatively high with other types of bricks.
The low compressive strength of RPMW brick is due to low
silica content, thus results in low binding capacity.

STUDY OF VARIATION OF PARTICLE SIZE OF RPMW
The compressive strength obtained for the RPMW bricks were found to be
less than the standards.
Thus study was further extended by changing the particle size of the
RPMW.
The particle sizes of RPMW was decreased as 4.56,2.36,1.18,0.150 mm .
As the particle size is reduced, the strength of the bricks get increased.
The maximum compressive strength was observed for 80:20 ratio brick for
both the cement and laterite brick. Thus, particle variation was done for
this proportion.
The 14th day compressive strength was tested and tabulated

COST ESTIMATION OF RPMW BRICK
The cost of the RPMW bricks is comparatively less than the
conventional bricks
As the raw material is obtained free of cost from the Punalur Paper
Mills, the cost of only transportation is considered.
The manufacturing can be under taken by unskilled labours.
The cost of fabrication of the mould is a onetime cost.
The cost of manufacture includes transportation charge of RPMW,
labour cost and cost for cement.
66
Cost of conventional bricks = 9 Rs
Proportion of brick (RPMW-cement) = 80:20
Total weight of one brick = 1.700 kg
Weight of materials used for one brick is;
RPMW = 1.360 kg
Cement = 0.340 kg
Cost calculation of each materials
RPMW = 0.60 Rs /kg = 1.36 x 0.6 = 0.816 Rs/brick
Cement (bag) = 400 Rs/bag = 8 Rs/kg = .340 x 8 = 2.72 Rs/brick
Labour cost = 600/1000 bricks = 0.6 Rs /brick
Other expenses = 0.5 Rs /brick
Total cost = Cost of (RPMW + cement + labour cost + other cost)
= 0.816 + 2.72 + 0.6 + 0.5 = 4.636 Rs
67
CONCLUSIONS
The bricks made from RPMW is found to have compressive strength
less than conventional brick.
It is observed that when the amount of cement is increased the
strength also increases.
In our project, the maximum compressive strength was obtained for
RPMW cement brick with 80:20 proportions.
The strength effect on the particle size was also investigated to
improve the strength of brick. It showed a positive result, as the size
of the RPWM particles is reduced, strength is increased.
68
RPMW from Punalur paper mill are found to have silica content only
about 20%. As the silica content in the raw materials is less it affects
the binding property of the particle .
The average weight of the RPMW –cement brick was found to be 1.6
kg which is much less than that of conventional brick .This bricks
are produced without firing which is an advantage over other
manufacturing of bricks in term of low embodied energy material.
The water absorption of RPMW-cement and RPMW-laterite bricks
are increasing with increase in percentage of RPMW.
RPMW-cement and RPMW-laterite bricks passed the efflorescence,
hardness and soundness tests successfully.
69
RECOMENTATIONS FOR FURTHER STUDY
1. In our project while increasing the percentage of cement we get a positive
result. Therefore, we accept an increase in compressive strength by
increasing the amount of cement.
2. Also when decreasing the particle size, the compressive strength is
increasing. This is due to the increase in binding property between the
materials.
3. Required strength can be achieved by adding proper admixtures.
4. The silica content of the RPMW collected is comparatively less. So
adding materials with high silica content may also increase the strength of
the brick.
