INTRODUCTION
Concrete :-
Concrete is considered world most use construction materials and they
form with homogeneous mixture of cement, fine aggregate, coarse aggregate and water with
proper proportion.
In this experimental work we focus on the coarse aggregate in concrete.
We partially replace coarse aggregate by waste bricks. And we replace waste bricks in various
percentage like 0% ,20%, 30%.

4.
WASTE BRICKS :
Waste bricks are rejected bricks which are either over
burned or not in shaped according to specification and the best way to recycle
these bricks is by using them in making concrete.
Over burn bricks or rejected bricks.

5.
NEED OF STUDY
For this replacement we choose waste bricks because of their
availability. The waste bricks are available from bricks manufacturing area. also
in brick making a large number of bricks are rejected due to non conformity with
the specification one such major nonconformity is the distorted form of brick
produced due to the uneven temperature in kiln. The main constituent of the
concrete is cement ,fine aggregate coarse aggregate, and water replacing some
of these materials makes significant changes in cost as well as performance.
coarse aggregate filled almost 70% of volume in concrete the cost of coarse
aggregate rapidly increasing also the availability of the aggregate is getting
reduced the major cost of the concrete is belonged to the aggregate. These
waste bricks is can also be a potential source of coarse aggregate.

6.
AIM & OBJECTIVE
1) Determine the mechanical strength of concrete by replacing coarse aggregate
with waste bricks.
2) Determine the behavior of fresh concrete after partial replacement of coarse
aggregate with waste bricks.
3) To find out optimum percentage of waste brick for maximum compressive
strength.

7.
METHODOLOGY
Mix proportion :
The batching of all ingredients was performed by weight.
The sand was air dried in the laboratory before mixing. First the surface of
damped with water then all the aggregate ( natural coarse aggregate ,fine
aggregate and waste bricks aggregate ) were spread on the surface area till
the aggregate.
After through mixing of aggregate cement was introduced
on the ground surface and water were added slowly as per W/C ratio. The
concrete was mixed for approximately three minutes after the water was
added.

8.
MIX CASTING :
We use M20 grade of concrete for this replacement. It is
found that the waste bricks base concrete is dark in color and is cohesive.
The amount of water in the mixture plays important role on the behavior of
fresh concrete. When the mixing time is long , mixture with high water
content bled and segregation of aggregate and the past occurred . This
phenomenon is usually followed by low compressive strength of hardened
concrete. From the preliminary work, it was decided to observe the
following standard process of mixing in all further studies.
1) Take the suitable proportion of the ingredients of the concrete.
2) Spread the fine aggregate on ground .
3) After that put the coarse aggregate as well as waste bricks .
4) After that add the water in suitable quantity.
5) And continue the wet mixing for another four minutes.
6) Then the fresh prepared mix was casting in standard cube molds.

9.
Curing :
All the mold were cured by immersing in a curing tank in
the lab the specimen were brought out from water approximately 24
hours before testing and kept at room temperature till testing.
Following test were conducted for this experimental work
a) Workability test
b) compressive strength test

LITERATURE REVIEW
2.1 Mr. G. S patil and Mr. P. B. Autade : have reported effect of replacement of course
aggregate by jhama class brick in concrete and to developed a mixture proportioning
process to manufacture jhama class brick base concrete and to identify study the effect of
silent parameters that affect the properties of jhama class brick based concrete and to study
the short term engineering properties of fresh and Hardened jhama class brick based
concrete.
2.2 Dr. M. N. hirenath and Mr. Sanjay S. J : have reported replacement of course
aggregate by demolished brick waste in concrete and to determine the suitabilty of brick
waste as replacement of course aggregate in concrete production and discuss on investigate
the mechanical and physical property of brick waste concrete and to compare the
performance between concrete with brick waste as course aggregate partially replacement
and conventional concrete This research is focus on some properties and strength behavior
of concrete if demolised waste brick used as aggregate in construction.

11.
2.3 Gopinandan dev and joyanta pal have reported on use of brick aggregate in
standard concrete and its performance in elevated temperature. Crush brick can be used
satisfactorily to produce M-25, M-30 keeping water cement ratt in range of 0.35 to 0.45
2.4 Bidve ganesh shivkant and G. N shete. Discuss about experimental study on effect
of partially replacement of course aggregate by over burn brick backs concrete is chipper
than conventional concrete 3% increment in the Compressive strength is found 20%
replacement of course aggregate by over burnt brick bat waste and strength decrease by
3.3% when the 40% of course aggregate is replace by over burnt brick bat waste, by
using aggregate cement ratio is 4.2 water cement ratio is 0.45 current study concluded
that over brunt brick bat waste can replace course aggregate up to 20 %

12.
2.5 Akshay N kadu and PM kulkarni : discuss about of partial replacement of over
brunt brick. This research is basically study to development, the manufacture and physical
properties of the concrete made by over brunt brick and demolished brick as a course
aggregate from this chapter present the environment which upraise the utilization of some
alternative materials of course aggregate in concrete at the time of brick manufacturing
maximum number of brick are rejected due to non - Comformity with the required
specification this rejected and waste brick can also be a potential source of course
aggregate.
2.6 Durga chaitnya and kumar jagarapu. Alternative course aggregate in concrete they
review the various admixture utilize in concrete like cocot shell rubber waste e - waste
and jhama brick concrete made by utilizing jhama block as course total, at first
invigorates the elevated compressive for the substitution 20% and 20 later that it
diminished by 60% and 80%

13.
Cement is a fine, grey powder. It is mixed with water and materials such as
sand, gravel, and crushed stone to make concrete. The cement and water form
a paste that binds the other materials together as the concrete hardens.
Ordinary Portland cement 53 grade was used for preparation of all concrete
cubes.

COARSE AGGREGATE:
The size of aggregate bigger than 4.75 mm is
considered as coarse aggregate. There are different types of shape of coarse

Bricks is a durable building materials and
construction materials with good load bearing properties various research have
been carried out in porosity, permeability and absorption of brick. The
traditional clay bricks are manually produced by pressing clay with certain
amount of sand in the wooden mould. Then the wet bricks are first dried in the
sun and air then transported to brick kiln for subsequent burning process the
brick are burn upto 800 to 900 C the brick kiln. If the temperature in kiln is

CONCLUSION
After the completion of project and final testing of cubes after 28 days And on
the basis of results obtained during the experimental investigation, following.
The compaction factor decreased as the percentage of waste bricks increased.
The unit weight also decreased as the percentage of waste bricks increases in
comparison with conventional concrete.
Concrete made by using waste bricks as a coarse aggregate, it gives better strength
for replacement of 20 % in M 15 grade of concrete.
Compressive strength was decreases after adding 30 % of waste bricks aggregate by
the replacement of stone aggregate in M 15 grade.
In M15 grade of concrete it gives high strength as compared to M20 grade of
concrete and it is suitable up to 20% replacement.
Use of such waste materials not only cuts down the cost of construction, but also
contributes in safe disposal of waste materials.
