3. INTRODUCTION
• Lightweight concrete can be defined as a type of concrete
which includes an expanding agent in that it increases the
volume of the mixture while giving additional qualities such as
nailbility and lessened the dead weight. It is lighter than the
conventional concrete.
• The present investigation aims in the study of properties of concrete
in which Styrofoam is used as a partial and full replacement for
natural sand.
• The basic strength properties of concrete were investigated replacing
fine aggregate by EPS.
4. MANUFACTURING OF EPS
• Raw beads are expanded using steam CURUL in large bags
before being convert in mould.
• Once in the mould the pre-puff beads are again steam to form a
block
• The blocks are then place on the storage floor to aged for the
appropriate length for before being cut it into various shapes and
sizes .
• Blocks are produced of several densities to meet specific project
needs.
5. EPS BLOCKS
Expanded Polystyrene (EPS) is a rigid, closed
cell, thermoplastic foam material produced from
solid beads of polystyrene, which is polymerised
from styrene monomer and contains an expansion
gas (pentane) dissolved within the polystyrene
bead.
TYPES OF EPS:-
1) Polystyrene Foam
2) Regular Polystyrene Plastic
3) Polystyrene film

7. NEED OF STUDY
Long-term performance
• The long-term performance is one of the most concerning issues
when introducing EPS beads in concrete materials.
Recycle EPS waste
• Recently, many studies have been developed using the EPS waste
recycled back into concretes with the aim of reducing
environmental impacts
Challenges against current global environmental
concerns
• The performance of the utilizing cement systems containing EPS
beads is extensively studied and reported.
8. OBJECTIVE
To gauge the strength and workability of concrete made using
replacement of fine aggregate by EPS of 1%, 1.5 %, 2 % , 4% &
6%.
• Workability test by slump cone.
• Compressive strength test.
• Durability by water absorption test.
• Comparing above three materials by conducting slump cone test
for workability, compressive strength test for compressive load,
and water absorption test for durability.
9. • The result will be presented in form of graphs and chart for
replacement with fine aggregate as a 1% , 1.5% , 2% , 4% and
6% .
• Further we will do the rate analysis for different materials.

1. Investigation of EPS Concrete 2016 Vishakh T. M,
Dr. Vasudev R.
Vishakh T. M, Dr. Vasudev R. discussed about the
production and application of EPS along with
environmental concern. They stated in this article
Lightweight concrete is better fire-resistant and
less heat transmitted through it. It is cost saving
and makes the structure more sustainable as it is
durable and no plastering and cladding is required.
2. Experimental study on properties of light
weight sandwich concrete blocks using
EPS sheets
2006 Elamurugu.P ,
Vijay Sarathy.R
The Researches made by different experts, show
that, partial replacement of coarse aggregate will
decrease the strength slightly. Durability of the
concrete also has an increased value.
3. Crushed EPS in Light weight concrete 2020 Nikita Sharma,
Gaurav Suthar,

The key point of attraction in light weight concrete
is its low density and thermal conductivity as
formation of voids with air entrapping takes place
because of low density high volume aggregates.
Compressive strength shows directly proportional
relationship with density of the mix as for less
densified mix, compressive strength decreases and
vice-versa.

The effect of polystyrene aggregate size on
strength and moisture migration characteristics of
light weight concrete. The study covers the use of
expanded polystyrene (EPS) and unexpanded
polystyrene (UEPS) beads as light weight
aggregate in concrete that contains fly ash as a
supplementary cementitious material.
Lightweight concrete with wide range of concrete
densities (1000-1900 kg/m3) were studied mainly
for compressive strength, split tensile strength,
moisture migration and absorption. The results
indicate that for aggregate size and concrete
density, concrete with UEPS aggregate exhibited
70% higher compressive strength than EPS
aggregate.
5. Sustainable Construction Using EPS
Beads in Light Weight Blocks to form
Innovative Foam Concrete as a Green
Building Material
2009 R. Gawale et al.
2016
Performed explores and considered that
thickness, compressive quality of the examples
with EPS dots and the examples without EPS dots
in the blend plan. Admixture Polycarboxyl ate
ether (PCE) is included blend configuration to
build the functionality of the solid. The ends were
discovered to be that quality of light weight solid
utilizing EPS globules is low for lower thickness
blend. This brought about augmentation of voids
all through the example brought about by the Air
entraining admixture. Along these lines the
decline in compressive quality of the solid.
12. METHODOLOGY
Stage 1: Theoretical Content
A comprehensive literature review is made to understand the
previous efforts, which include the review of textbooks,
periodicals and academic journals, seminar, conference and
research papers.
Stage 2: Main Research
The methods followed to achieve the objectives are:
Assessment on the existing mix design methods and test results
of concrete produced using crushed EPS will be conducted.
13. The fine aggregate has been replaced by used Crushed EPS
accordingly in the range of 1%, 1.5%, 2%, 4% & 6% by weight for
M-25 grade concrete.
Total 15 cubes will be casted during the project. Test will be
conducted on this cubes and observation will be taken.
Test Conducted on Concrete are :
Test conducted on fresh concrete:
1.slump cone test- This test is conducted to check the workability of
concrete.
Test conducted on hardened concrete:
1.compressive strength test: This test was conducted to check the
compressive strength of concrete at 28 days.
14. The results will be presented in forms of graphs and charts.
Based on the findings conclusions will be made and
recommendations will be suggested.
