ABSTRACT

Many studies has been conducted on the

utilization of waste products in Mortar andconcrete.The use of waste products for making

mortar and concrete,not only the cost of

construction can be bring down,but also it will

give a solution for the safe disposal.In this

paper the garbage paper pulp along with

quarry dust was used for making mortar and

concrete.The use of paper pulp and quarry dust

was used to replace partially the cement and

the fine aggregate.From the studies conducted

in the laboratory it shows siginificant

improvement with respect to compressive

strength,water absorption and static bending

test

INTRODUCTION

Concrete is the most common building material

for many years.It is a construction material

which consists of cement,aggregate and

water.Many reaserch work has been taken up

to lower the cement content and use suitable

material to replace fine aggregate and the

coarse aggregate.Many waste material are

available in nature which poseshealth problems

if it is dumped in the landfills. Flyash which is

obtained from burning a coal posses pozzolanic

properties and can be used as a replacement

material for cement.These material if it is notused properly poses environmental problem.

By products which is obtained from different

industries produce different waste materials, if

this is not deposited safely it poses different

environmental problem.About 35% of

municipal solid waste by weight is paper andpaper products(wikipedia).World wide

consumption of paper has risen by 400% in the

paste 40 years leading to increase in

deforestation with 35% of harvested trees

being used for paper manufacture(wiki

pedia).paper has alaways been essential part

of our classrooms whether it be taking

otes,handouts,assignmentsor tests,they all use

paper. Paper usage is inevitable in all levels of

schools(pays to live green)

With this background, in this work paper pulp

and quarry dust are used to prepare mortar

and concrete so that it will be useful for making

low cost material

1. LITERATURE REVIEW

2. R.Srinivasn,K.Sathiya and

M.Palanisamy has made study on use

of hypo sludge for making partial

replacement of cement.They studied

that the hypo sludge cotains low

calcium and maximum calcium chloride

and minium amount of silica. Hypo sludge

behaves like cement because of silica and

magnssium properties and this will improve

the setting of concrete.In the experimental

study 150*150*150 mm concrete cubes

were casted using M25 grade concrete

specimens with oridinary portland cement

and ordinary portland cement replaced

with hypo sludge at

10%,20%,30%,40%,50%, and 60% levelswere cast. The addition of hypo sludge

shows a marginal improvement in altering

ultimate compressive strength of the

cubes.The split tensile strength should be

decreased when the percentage of the

replacement is increased.The addition of

hypo sludge reduces the cost of making

concrete marginally.Finally they conclude

that the replacement of cement with hypo

sludge provides maximum compressive


4/6

strength at 30% replacement. J R .

PITRODA and F S UMRIGAR studied the use

of fly ash and hypo sludge in concrete

formulations in making traditionalconcrete.They studied that the modulus of

elasticity of concrete is a very important

property to determine the deflection of the

structural elements.The hypo sludge from

J.K.paper mill pvt Ltd, Tappi district was

used for this study.The cement has beenreplaced by fly ash and hypo sludge in the

range of 10%,20%,30% and 40% by weight

of cement for M25 and M40 mix. Concrete

mixtures were produced, tested and

compared in terms of modulus of elasticity

with conventional concrete for 56 days

water curing.From the study they

concluded that the modulus of elasticity

decreases with % replacement of fly ash

and hypo sludge.The use of fly ash and

hypo sludge produces a greener concrete

for construction.From this study they

concluded that fly ash and hypo sludge canbe used as a construction

3. material where less strength is required.

4. Sumit A Balwaik,S.P Raut has studied the


5/6

use of paper-mill pulp in concrete

formulations as an alternative to land fill

disposal.The cement has been replaced by

waste paper sludge accordingly in therange of 5% to 20% by weight for M20 and

M30 mix.concrete mixtures are produced

and compared in terms of slump and

strength with the conventional

concrete.The concrete specimens were

tested for compression test,splitting tensiletest and flexural test.Based on the results it

was found that addition of waste paper

pulp increases the compressive ,splitting

tensile and flexural strength up to 10%

marginally and further the addition of

waste paper pulp reduces the strength

gradually. The concluction were drawn

5. 01. The most sutiable mix proportion is the

5 to 10% replacement of waste paper pulp

to cement.

6. 02. There was increase in water absorption

of the concrete mixes as the content of thepaper pulp increased.

7. Finally they derived that the use of waste

paper pulp in concrete can save, the pulp


6/6

and the paper industry disposal costs and

produce greener concrete for construction.
