The rising cost of material is a matter of concern in this developing construction environment. The prices of building material such as cement, sand, gravel etc. are increasing day by day. The reason for increase in cost is high demand and less availability of material. Nowadays, most of the researchers are doing research on the material which can reduce the cost of construction as well as increase the strength. Research on waste material such as fly ash, rice husk, slag and sludge from treatment of industrial and domestic waste water demolished building material is being done. Use of coconut shell in concrete is not only useful economically but also environmentally useful for human being. Coconut shell is one of the main contributors of pollution problem as a solid waste. Coconut shell used as coarse aggregate in concrete encouraged sustainable and environmentally helpful material in the construction field. Since cement rate increases day per day and its availability is decreasing as per time so it can be useful to use coconut shell ash used as substitute of cement in concrete. Coconut shell can be used in the form of powder with epoxy resins or epoxy matrixes in concrete also. Composites are made by combining two or more natural or artificial materials to maximize their useful properties and minimize their weaknesses.
STUDY ON STRENGTH PROPERTIES OF COCONUT SHELL CONCRETEIAEME Publication
Concrete is the premier construction material around the world and is most widely used in all types of construction works, including infrastructure, low and high-rise buildings, and domestic developments. It is a man-made product, essentially consisting of a mixture of cement, aggregates, water and admixture(s). Inert granular materials such as sand, crushed stone or gravel form the major part of the aggregates. Traditionally aggregates have been readily available at economic prices and of qualities to suit all purposes. But, the continued extensive extraction use of aggregates from natural
resources has been questioned because of the depletion of quality primary aggregates and greater awareness of environmental protection.
The high cost of materials for anyconventional
building is a major factor that affects the housing delivery
worldwide. This has necessitated research for alternative cost
effective materials in construction. The paper aims at analyzing
characteristic compressive and tensile strength of coconut shells
of concrete produced. By partial replacement using crushed,
granular coconut shells as a substitute for conventional coarse
aggregate in M20 grade concrete. The cube and cylinder are
casted, tested then physical and mechanical properties are
determined. In this studies, three different concrete mixes with
different the combination of natural material content namely
0%, 25%, 50%. Three samples specimen will be prepare for each
concrete mixes. The parameters will be tested are compressive
strength, tensile strength.
This paper analyzed an investigation on the behavior of
concrete specimens produce from coconut shell aggregate. A total
of 36 specimens with varying percentage of replacement were
casted and tested. The attempt is made to prove in all respect the
serviceability and durability, experimental study is satisfying and
can be implemented in rural areas by considering all technical

Comparative Analysis of Coconut shell Concrete to Traditional ConcreteCompara...IJRTEMJOURNAL
It is found that so many wastes which can be used in traditional concrete like e-wastes, rubber
tyre waste, glass waste etc. The coconut shell is also a main waste which can be used in traditional concrete.
Generally, coconut shells are used in traditional concrete in the form of viz., coconut shell aggregate and
coconut shell fiber. This paper describes coconut shells are used as replacement of coarse aggregates. The
compressive and flexural strength test where taken on 10%, 20% and 30% replacement of coarse aggregate to
coconut shells. It is observed that the compressive strength of concrete is reduced in some extent and the
flexural strength also reduced as replacement of coconut shell is increased, but the 10% replacement is possible
to use in construction work and 20% and 30% replacement are possible to use for less important construction
work under some conditions.
It is found that, workability of concrete is increased than traditional concrete as percentage replacement is
increased. Total cost of concrete is get reduced by replacement of coarse aggregate to coconut shells. The
volume of concrete is also increased as replacement is increased, hence, the total quantity of concrete required
is getting reduced and the cost is again getting reduced. This paper supports the “SWACHHA BHARAT
ABHIYAN” carried by our Hon. Prime Minister Narendra Modi.
Finally, this paper concluded that, the Coconut Shell is possible to use for construction work as coarse
aggregate under some conditions economically. It is majorly used for construction of small huts, watchman
cabin, farm house in forest areas and small houses etc.

In this research work experiments have been conducted with collection of materials required and the data required for mix design are obtained by sieve analysis and specific gravity test. Sieve analysis is carried out from various fine aggregates (FA) and coarse aggregates (CA) samples and the sample which suits the requirement is selected. Specific gravity tests are carried out for fine and coarse aggregate. The various materials used were tested as per Indian standard specifications. On the basis of the experimental studies carried out on M30 grade concrete as partial replacement of coarse aggregates with sea shells and coconut shells, the following conclusions are drawn from the above experiment we conclude that comparing to traditional concrete, compressive strength of 10% (5% + 5%) of coconut shells (5%) and sea shells (5%) increased. whereas the compressive strength of the concrete cubes has gradually decreased from addition of 10% (5% + 5%) of coconut shells and sea shells. Hence for economical view 10% is preferable and in the perspective of compressive strength 10% is suggested. Thus, 10% replacement coconut shells and sea shells are recommended for both heavy weight and light weight concrete production.
Experimental Study of Partial Replacement of Fine Aggregate with Waste Materi...IJRES Journal
The utilization of industrial and agricultural waste produced by industrial process has been the focus of waste reduction research for economical, environmental and technical reasons. This is because over 300 million tones of industrial waste are being produced per annual by agricultural and industrial process in India. The problem arising from continuous technological and industrial development is the disposal of waste material. If some of the waste materials are found suitable in concrete making not only cost of construction can be cut down, but also safe disposal of waste material can be achieved. The cement of high strength concrete is generally high which often leads to higher shrinkage and greater evaluation of neat of hydration besides increase in cost. A partial substitution of cement by an industrial waste is not only economical but also improves the properties of fresh and hardened concrete and enhance the durability characteristics besides the safe disposal of waste material thereby protecting the environment form pollution This paper deals with partial replacement of fine aggregate with the industrial waste from China Clay industries. The compressive strength, split tensile strength and flexural strength of conventional concrete and fine aggregate replaced concrete are compared and the results are tabulated.

Abstract
The Growth in the Electronics sector has been rapid and this rapid growth is due to continuous upgradation of technology and introduction of new technologies to the market. This has led to one of the fastest growing solid waste in the world, simply called as E-waste. India is the 5th highest e-waste producer in the world. The rapid increase in the construction activity in India, has resulted in huge demand for the aggregates to be used in the concrete. This has led to depletion of natural resources and adverse changes in the environment. This rapid development in the infrastructure sector has led to shortage of natural sand. This paper outlines the experimental work carried for utilisation of e-waste as a partial replacement for the fine aggregates. Strength tests and durability tests are conducted on hardened concrete. Results show that the partial use of E- waste as fine aggregates results in much higher workable and less dense concrete. This study gives an Economic, environment friendly and efficient disposal method for E-waste to be used as a partial replacement to the fine aggregates in concrete.

Use of Over-Burnt Bricks as Coarse aggregate in ConcreteEditorIJAERD
In modern construction industry number of materials are used and one of the materials is Brick. Regular
bricks are generally used in buildings or in some other engineering applications. In manufacturing of these bricks, a lot
of waste is produced in the form of over- burnt-bricks. The bricks being near to the fire in the furnace receives a
temperature more heat and eventually shrink and loose its shape, its color becomes reddish. These bricks can’t be used
in construction, directly because of their distorted shape dark color. hose over-burnt brick could be a source of recycled
coarse aggregate. The primary goal of this paper is to assess the suitability of incorporating over-burnt bricks in
concrete, by the partial replacement of natural coarse aggregate (NCA) with overburnt brick aggregate (OBBA) in a
ratio of 20%, 50%, and 100%. Initially, mix proportion of 1:2:4 and w/c of 0.57 was selected. By replacing NCA with
OBBA while using mix proportion of 1:2:4 and w/c of 0.57, the resulting concrete was found non-mixable and nonworkable. Thus, mix was designed (for targeted strength of 4ksi) for all replacement percentages. Slump test was
conducted for each replacement and the results show that by increasing replacement percentage the workability of
concrete decreases. the slump values are in between the range of 3–1.5 inches. For compressive strength the cylindrical
specimens of 6" x 12" were tested at 3, 7, and 28 days. For 20% replacement, the loss in compressive strength is 42.16%
for 3 days and for 7 and 28 days the loss is 46.96% and 61.37% respectively. For 50 % replacement, the loss in strength
for 3, 7 and 28 days is 29.73%, 30.87% and 58.29% respectively. For 100% replacement, the loss in strength for 3, 7 and
28 days is 48.65%, 55.65% and 69.19%.

Abstract This paper presents the results, obtained after replacement of fine and coarse aggregates, in concrete mix, with tyre rubber. The tyre rubber, which has been used in the present study, is obtained after the mechanical trituration process of post – consumed tyres from trucks. Researchers have investigated, over the years, the use of recycled tyre rubber waste as a replacement for aggregate in concrete and its effectiveness. “Rubcrete-Mix” which would result from such replacement is found to have many engineering applications and holds promise in future. Rubcrete also possesses good mechanical properties and is considered to be one of the best and economical ways of recycling the used tyres. The present experimental study has the aim of arriving at the optimum quantity of the replacement material for the aggregates in concrete mixtures, for various engineering applications. For achieving a proper bond with the surrounding concrete paste, the recycled aggregates have been designed with respect to their size, shape and gradation. With the water – cement ratio being kept constant fine and coarse aggregate has been replaced with tyre rubber powder and chipped rubber and also cement has been replaced with silica fume. In preparing the concrete, Portland slag cement has been used along with super plasticizer less than 1% by weight of cement to achieve required workability of the resulting concrete. Furthermore, durability studies have been conducted and mixes have been designed for M30 grade concrete. Keywords: Concrete Mix, Mechanical Properties, Rubber Powder, Chipped Rubber, Silica fume.

Rice Husk Ash Sandcrete Block as Low Cost Building MaterialIJERA Editor
Concrete is a widely used construction material for various types of structures due to its structural stability and
strength. The construction industry is today consuming more than 400 million tonnes of concrete every year
.Most of the increase in cement demand will be met by the use of supplementary cementing materials, as each
ton of Portland cement clinker production is associated with similar amount of CO2 emission, which is a major
source of global warming. Partial replacement of ordinary Portland cement with mineral admixtures like fly ash,
ground granulated blast furnace slag, silica fume, metakaolin, Rice husk Ash (RHA),etc with plasticizers
eliminates these drawbacks. The use of rice husk modifies the physical qualities of fresh cement paste as well as
microstructure of paste after hardening. By burning the rice husk under a uncontrolled temperature in the
atmosphere, a highly reactive RHA was obtained and the ash was utilized as a supplementary cementing
material. This paper presents the effects of using Rice Husk Ash (RHA) as a partial cement replacement
material in mortar mixes. This work is based on an experimental study of mortar made with replacement of
Ordinary Portland Cement (OPC) with 10%, 20% 30% & 40% RHA. The properties investigated were the
compressive strength, setting time, consistency, workability and specific gravity. Finally, a cost analysis was
also done to compare the efficiency of rice husk ash sandcrete blocks. From the test results it can be concluded
that rice husk ash can be utilized in day today life of manufacturing building blocks which are more economical
and more eco-friendly than the cement concrete blocks which are produced now-a-days
Effect on Concrete Strength by Partial Replacement of Cement with Cotton Stal...ijtsrd
Huge quantity of Cotton stalk ash and rice husk ash are generating as a waste product in agriculture sector in India and many other developing countries every year. In lack of proper wakefulness and technology expansion, great portion of these by products remain unutilized causing severe disposal and environmental troubles. The main goal of this thesis is to examine the performance of M40 grade concrete with a mix ratio as per M40 grade and a water cement ratio of 0.425 Additionally, it aims to determine the compressive strength, flexural strength, and split tensile strength of concrete cement when cotton stalk ash and rice husk ash are used in place of cement. With various percentage like 10, 20, and 30 etc. of cotton stalk ash and rice husk ash well as with combined replacement of Cotton stalk ash and rice husk ash. and results that the workability of concrete was found to be reduced on enhance the Cotton stalk ash CSA , rice husk ash RHA by difference percentages. The Maximum increase in 53.67 N mm2 of compressive strength is obtained after the period 28 days with cotton stalk ash substituting 10 of the cement CSA . The maximum increase in flexural strength over the period of 28 days was 5.98 N mm2, with cotton stalk ash substituting 10 of the cement CSA . When 10 of the cement is replaced with cotton stalk ash, the significant increase in split tensile strength for 28 days is 4.23N mm2 CSA By substituting cotton stalk ash, rice husk ash for 20, 10 of the cement, the compressive strength as per this investigations for 28 days is observed 49.47 N mm2 CSA, RHA is not achieved highest value but achieve the target mean strength. The greatest results are achieved when cotton stalk ash are utilized, although at different percentages.

Cement is a major construction material worldwide. However, given the escalating costs of cement and the environmental hazards associated with the use of cement there is need to develop alternative, costeffective, non-conventional, locally available materials, especially those that can partially or wholly replace cement. This paper presents the results on the study of the effect of local brewery waste and bitter cassava flour on the compressive strength and shrinkage of plaster. The test was made with cement replaced by local brewery waste or bitter cassava (10-50%) and cement/sand mix as a control. The results showed an optimum of 20% cement replacement with bitter cassava for plaster mortar for high cost houses (18.1Mpa) and 10% cement replacement with local brewery waste for plaster mortar for low cost houses (2.1Mpa). Result show a maximum shrinkage of 8mm at 50% replacement with bitter cassava and zero shrinkage for 50% replacement with local brewery waste. Furthermore only the control, 40% and 50% with bitter cassava flour showed cracks of about 2mm for mix ratio 1:3 and 1:4.

Making model of dual axis solar tracking with Maximum Power Point Trackingijsrd.com
Now a days solar harvesting is more popular. As the popularity become higher the material quality and solar tracking methods are more improved. There are several factors affecting the solar system. Major influence on solar cell, intensity of source radiation and storage techniques The materials used in solar cell manufacturing limit the efficiency of solar cell. This makes it particularly difficult to make considerable improvements in the performance of the cell, and hence restricts the efficiency of the overall collection process. Therefore, the most attainable maximum power point tracking method of improving the performance of solar power collection is to increase the mean intensity of radiation received from the source used. The purposed of tracking system controls elevation and orientation angles of solar panels such that the panels always maintain perpendicular to the sunlight. The measured variables of our automatic system were compared with those of a fixed angle PV system. As a result of the experiment, the voltage generated by the proposed tracking system has an overall of about 28.11% more than the fixed angle PV system. There are three major approaches for maximizing power extraction in medium and large scale systems. They are sun tracking, maximum power point (MPP) tracking or both.

Reducing Silicon Real Estate and Switching Activity Using Low Power Test Patt...ijsrd.com
Power dissipation is a challenging problem for today's system-on-chip design and test. This paper presents a novel architecture which generates the test patterns with reduced switching activities; it has the advantage of low test power and low hardware overhead. The proposed LP-TPG (test pattern generator) structure consists of modified low power linear feedback shift register (LP-LFSR), m-bit counter, gray counter, NOR-gate structure and XOR-array. The seed generated from LP-LFSR is EXCLUSIVE-OR ed with the data generated from gray code generator. The XOR result of the sequence is single input changing (SIC) sequence, in turn reduces the switching activity and so power dissipation will be very less. The proposed architecture is simulated using Modelsim and synthesized using Xilinx ISE9.2.The Xilinx chip scope tool will be used to test the logic running on FPGA.
Defending Reactive Jammers in WSN using a Trigger Identification Service.ijsrd.com
In the last decade, the greatest threat to the wireless sensor network has been Reactive Jamming Attack because it is difficult to be disclosed and defend as well as due to its mass destruction to legitimate sensor communications. As discussed above about the Reactive Jammers Nodes, a new scheme to deactivate them efficiently is by identifying all trigger nodes, where transmissions invoke the jammer nodes, which has been proposed and developed. Due to this identification mechanism, many existing reactive jamming defending schemes can be benefited. This Trigger Identification can also work as an application layer .In this paper, on one side we provide the several optimization problems to provide complete trigger identification service framework for unreliable wireless sensor networks and on the other side we also provide an improved algorithm with regard to two sophisticated jamming models, in order to enhance its robustness for various network scenarios.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Abstract— The rising cost of material is a matter of concern
in this developing construction environment. The prices of
building material such as cement, sand, gravel etc. are
increasing day by day. The reason for increase in cost is
high demand and less availability of material. Nowadays,
most of the researchers are doing research on the material
which can reduce the cost of construction as well as increase
the strength. Research on waste material such as fly ash, rice
husk, slag and sludge from treatment of industrial and
domestic waste water demolished building material is being
done. Use of coconut shell in concrete is not only useful
economically but also environmentally useful for human
being. Coconut shell is one of the main contributors of
pollution problem as a solid waste. Coconut shell used as
coarse aggregate in concrete encouraged sustainable and
environmentally helpful material in the construction field.
Since cement rate increases day per day and its availability
is decreasing as per time so it can be useful to use coconut
shell ash used as substitute of cement in concrete. Coconut
shell can be used in the form of powder with epoxy resins or
epoxy matrixes in concrete also. Composites are made by
combining two or more natural or artificial materials to
maximize their useful properties and minimize their
weaknesses.
Keywords: coconut shell, coconut shell ash, epoxy matrixes
or composites, coconut shell powder, cement, coarse
aggregate
I. INTRODUCTION
Many of the non-decaying waste materials will remain in the
environment for hundreds, perhaps thousands of years. The
non-decaying waste materials cause a waste disposal crisis,
thereby contributing to the environmental problems.
However, the environmental impact can be reduced by
making more sustainable use of this waste. This is known as
the Waste Hierarchy. Its aim is to reduce, reuse, or recycle
waste, the latter being the preferred option of waste disposal.
There were many experimental work conducted to improve
the properties of the concrete by putting new materials,
whether it is natural materials or recycle materials or
synthetic materials in the concrete mix. Concrete is an
artificial material similar in appearance and properties to
some natural lime stone rock. It is a man made composite,
the major constituent being natural aggregate such as gravel,
or crushed rock, sand and fine particles of cement powder
all mixed with water. The concrete as time goes on through
a process of hydration of the cement paste, producing a
required strength to withstand the load. The use of coconut
shell in concrete has never been a usual practice among the
average citizens, particularly in areas where light weight
concrete is required for non-load bearing walls, non-
structural floors, and strip footings. The chemical
composition of the coconut shell is similar to wood.
Coconut is grown in more than 93 countries. South East
Asia is regarded as the origin of coconut. India is the third
largest, having cultivation on an area of about 2.60 million
hectares. Annual production is about 7562 million nuts with
an average of 5295 nuts per hectare. The coconut industry in
India accounts for over a quarter of the world's total coconut
oil output and is set to grow further with the global increase
in demand. However, it is also the main contributor to the
nation's pollution problem as a solid waste in the form of
shells, which involves an annual production of
approximately 3.18 million tones. Coconut shell represents
more than 60% of the domestic waste volume.
II. OBJECTIVES
To find economical and environmental helpful
solution for high cost of concrete.
To discuss the use of coconut shell in the form of
ash as partial replacement of cement.
To discuss the use of coconut shell powder with
epoxy resins/epoxy matrixes/composites in

D. Use of Coconut Shell Ash as Replacement Of Cement
The cost of cement used in concrete works is on the increase
and unaffordable, thus the need to find alternative binding
materials that can be used solely or in partial replacement of
cement. One of the agricultural waste materials, coconut
shells are collected and burnt .in the open air (uncontrolled
combustion) for three hours to produce coconut shell ash
(CSA), which in turn was used as pozzolana in partial
replacement of cement in concrete production. The studies
showed that the density of concrete cubes for 10-15%
replacement was above 2400 Kg/m3
. The average density
decreases from 2525.5 Kg/m3
for OPC to 2314 Kg/m3
at
30% replacement. The density of cement is higher than that
of the CSA. The compressive strength meets the
requirement for use in both heavy weight and light weight
concreting. CSA meets the requirement for a pozzolana. The
setting times increases with increase in the amount of CSA.
The initial setting time increases from 1 hr 5 min at 0%
replacement to 3 hrs 26 min at 30% replacement while the
final setting time increases from 1 hr 26 min at 0%
replacement to 4 hrs 22 min at 30% replacement. The
pozzolanic activity index decreases with increasing
percentage replacement of OPC with CSA. The compressive
strength decreases with increasing percentage replacement
of OPC with CSA. The optimal 28 days strength for OPC-
CSA mix is recorded at 10% replacement is 31.78 N/mm2

E. Use Of Coconut Shell Powder With Epoxyresins/ Epoxy
Matrixes/ Composites In Concrete
The chemical composition of coconut shell powder having
Lignin (29.4%), Cellulose (26.6%), Pentosans (27.7%),
Solvent Extractives (4.2%), Moisture (8%), Uronic
Anhydrides (3.5%) and Ash (0.6%).The coconut shells
collected from local resoureces were crushed into small
pieces manually by using hammer. Then small pieces
converted into powder by same method. The collected
powder was then sieved to different sieve sizes.
Mechanical properties of coconut shell powder epoxy resin
are greatly affected by the how much volume filled by
coconut shell powder. Samples provided are on the 20 %, 30
%, 40 % coconut shell powder filled, from density point of
view it is observed that density of 20% CSP filled is less
than the other filled. When we go from 20% to 30 % density
curve increases gradually and when it goes to 40% from
30%, it increases more rapidly than other so from 30-40%
rate of increase in density is maximum.
Maximum tensile strength is obtained at 20% CSP
filed and it decreases as further increment in the ratio. Rate
of decreasing tensile strength is approximately constant
from 20% to 30% and from 30% to 40%.
Flexural strength of CSP composites increases
from 20 % to the 30 % of CSP filled and further it is
decreased for the 40 %. Flexural strength is minimum for
the 40% and rate of decrement in strength for 30-40% is
greater than rate of increment in flexural strength for the 20-
30%.
The composite prepared with 20% to 30% CSP
filled volume fraction is suitable for the application in the
interior part of an aircraft, motor car and automobilewhere
materials with good tensile strength, low density andlow
hydrophilic characteristic are required.
F. Use of Coconut Shell as Coarse Aggregate In Concrete
Using 1:2:4 proportions it is found that the density and
strength characteristics of concrete produced by volume
replacement of 20%, 30%, 40%, 50% and 100%
replacement of crushed granite with coconut shells were
investigated. It was concluded that
Increase in percentage replacements by coconut
shells reduced the strength and density of concrete.
With the exception of complete replacement, 20%,
30%, 40%, and 50% replacement of crushed
granite by coconut shells can be used in producing
lightweight concrete.
18.5% replacement of crushed granite with coconut
shells can be used to produce structural concrete
per the requirements.
Coconut shells can be used as partial replacement
of crushed granite or other conventional aggregates
in reinforced concrete construction.
Coconut shell can be used as partial replacement of
coarse aggregate in concrete.
At M-25 mix design it was reported development
of the mix design of lightweight aggregate concrete using
Coconut shell aggregate (CSA) as coarse aggregate together
with cement and river sand. The compressive strength after
28 days was found to be in the ranges between 4.9 N/mm2
-
23.5 N /mm2
under water curing. The test results shows that
concrete using coconut shell aggregate has resulted in
acceptable strength required for structural lightweight
concrete. It is concluded that the lightweight concrete
developed from CSA aggregate can be used for both
structural and non-structural applications. This study was
carried out to determine the possibilities of using coconut
shell as aggregate in concrete. They concluded water
absorption of the coconut shell aggregate was high about 24
% but the crushing value and impact value was comparable

to that of other lightweight aggregates. The average fresh
concrete density and 28-day cube compressive strength of
the concrete using coconut shell aggregate were 1975 kg/m3
and 19.1 N/mm2
respectively.
` At the different proportions, the compressive
strength of concrete cubes produced with gravel and coconut
shells, for seven (7) days curing, the average compressive
strength for concrete cubes produced with coconut shell of
mix ratio 1:2:4, 1:11/2
:3, 1:3:6 were 8.6, 8.9, 6.4 N/mm2
respectively and 15.1, 16.5, 11N/mm2
respectively for 28
days. The 7 days cured concrete cubes produced with gravel
have an average compressive strength of 19.6, 18.5, and 9.6
N/mm2
and 28.1, 30.0 and 15.6 N/mm2
at 28days with mix
ratios of 1:2:4, 1:11/2
:3, 1:3:6. From the research, mix ratio
1:11/2
:3 of coconut shell with strength 16.5N/mm2
at 28 days
can be used as plain concrete.
III. CONCLUSIONS
There are several conclusions from above study:
(1) Coconut shell can be used in concrete to solve
environmental and economical problem.
(2) Coconut shell can be as coarse aggregate in
concrete and it give enough strength to concrete as
its crushing value and impact value is better than
coarse aggregate. It can be grouped as light weight
aggregate and used at different proportion as per
required strength.
(3) Coconut shell ash can e used as the partial
replacement of cement in concrete and proportion
depends upon the strength required and quality of
coconut shell ( property of coconut shell).
(4) Coconut shell powder with epoxy resin/matrixes
can be used in concrete.
