3. Abstract
 In the world, concrete is material which is produced more than any other man made
material. Due to the increasing of population in the world, a waste material also
increases. In those waste materials many are non- degradable materials, they make
hazards to the environment . So , that usage of non degradable waste [1] in concrete
will be safe for disposal. This project will give the ideas, experimental analysis of the
partial replacement of e-waste and surrki (Coarse Aggregates) and partial
replacement of waste glass powder and sawdust (Fine aggregates). on the
concrete mix. Desired properties of concrete such as strength, specific gravity ,
workability ,durability , can also achieved by adding above materials in the concrete.
 A number of laboratory tests were carried out.
 These tests included workability, unit weight, compressive strength The main findings
of this investigation revealed that the four types of waste materials could be used as
partial substitutes for sand or coarse aggregates in concrete mixtures.
 Keywords : Powder of Waste Glass, Coarse Aggregate-Partial Replacement, Fine
Aggregate, Compression Test ,.

4. INTRODUCTION
Concrete is widely used in all constructions like
architectural structures , foundations , bridges, runways , dams. Its
usage in construction has been increased rapidly from time to time
. Concrete owes its unique position as the structural member .
In order to use some of the waste materials are
used i.e., some of the wastes are partial replacement of fine and
coarse aggregates. Cement commonly used as Portland cement
and E-wastes , glass powder , brick pieces and saw dust those
wastes are used to make concrete .
And test the concrete of its durability ,
strength, binding based on the compressive strength test.

5. Required Materials

Fine Aggregates are :-
Sand
Glass Powder
Saw Dust…
Coarse Aggregates are :-

6. Waste materials used in
concrete
 The partial replacement of fine aggregates by
 Glass Powder
 Saw Dust
 The partial replacement of coarse aggregates by
 E-Wastes
 Brick pieces

8. Collection of Materials
 We Collect a all type of materials are required for Concrete.
 E – Waste are made to small pieces.
 And collect a cement , fine aggregates and coarse
 aggregates.
Batching :-
The quantities of cement , F.A , C.A , and Water fro each
batch are measured by weighing balance of an accuracy
of 5 gm.

9. Workability Tests
 Slump cone test :-
 Slump cone test is commonly used for measuring the consistency of
concrete which can be employed either in laboratory or site work , By using
slump come apparatus.
 The mold is cleaned and placed in a smooth , rigid surface and the height
is filled with four layers and each layers gives 25 blows .
 It gives the condition of the mixed concrete proportion…
 Compaction factor test :-
 Compaction factor measures the workability in an indirect manner by
determining the degree of compaction.
 The sample of concrete is placed in the upper hopper to the drim.
 The trap door is released and the lower is allowed to fall on the cylinder ,
then it is fully compacted and weighed separately .
 The ratio of weight of fully compacted to the weight of partly compacted
concrete gives the compaction value…

11. Preparation of concrete
 By using all materials in which 2.5 % , 5% ,10% of
waste materials are used for making of 3 different
percentages
of concrete.

12. Casting
The molds are kept ready of dimensions are
15*15*15cm before preparing and mixing. Molds are cleaned and
oiled an oil contact surfaces then fixed with screws.
The concrete is filled into the molds in which
each layer is equally distributed in a uniform layer. Each layer gives
25 strokes by using tampering rod , at top of the concrete makes a
smooth surface.
After 24 hours the specimens or concrete
cubes are removed by the molds.

14. Concrete cubes

15. Curing
The concrete cubes are kept in a
water for testing purpose. The concrete cube is tested of
7 , 14 , 21 ,and 28 days .

16. Determine the compressive
strength
By using the compression testing
machine or universal testing machine to determine the
compressive strength of specimens .
The compressive strength of the
specimen shall be calculate by the maximum load applied
in the specimen during the test by the cross-section area
Compressive =
𝑀𝑎𝑥𝑖𝑚𝑢𝑚 𝑙𝑜𝑎𝑑
𝐴𝑟𝑒𝑎

17. Conclusions
The compressive strength of the
specimen is verified with the original compressive
strength of specimen without using waste materials.
After that we conclude an idea on
the project i.e., it is successful or failure project.
