ABSTRACT

The objective of this paper is that it Investigation [1] of effect on strength use of

Bagasse ash coated PET fibres in concrete at different percentages and reduces plastic

waste in the environment. To examine the possibility of using recycled plastic in

concrete mix. PET fibres are partial replacement by weight of cement with percentage

of 0%, 0.5, 1%, 1.5%, and 2%. PET fibre coated with epoxy binder .M40 grade of

concrete use for mix deign of concrete. Total 90 sample of moulds specimen [1] made

for testing and each sample has three moulds of specimen casted .After the testing

average vale of specimen is calculated and shown in given tables. Strength is increase

compare with the conventional concrete specimen’s replacement of coated fibre. The

testing of given specimen done in compressive machine and Flexural testing machine.

The increase of percentages of bagasse ash coated fibre in concrete is increase the

strength of concrete. The bonding strength of concrete is improve and cracks in concrete

decrease use of coated fibres and reduces the plastic waste. Strength is increase with

using bagasse ash coated PET fibbers in concrete.

1. INTRODUCTION

The plastic waste is non-biodegradable[7] material which is developing the big issues within

the surroundings the plastic call for increase every day and the boom of plastic industries are

increase our society and with the much less available area for land to disposal the waste .

The Bagasse Ash [12] is waste material [12] of sugarcane [12] miles. In this study [13]

Bagasse ash [13] was used for coating with epoxy binder. The bagasse ash passed a 150micron

sieve .the bagasse ash is increase the boding strength in concrete. Replacement [13] of cement

with Bagasse ash ratio 20% to 30% they increase strength 15 to 20% in concrete. Bagasse ash

reduces demand of cement. Bagasse ash [13] work as cement material in concrete.

Today the demand of construction is increase day by day and therefore the material use in

construction demand increase. Cement is nearly main material that use in construction .the

producing of cement industries is impact greenhouse gases. The cement business is one amongst

the first producers of CO2, a potent gas. The assembly of cement increase the greenhouse gases

and therefore the increase the temperature. Replacement of cement with plastic fibre with given

percentages they assist in cut back the plastic waste and simply safe atmosphere .The coated

fibres use in concrete to extend the strength in concrete as compare with convention concrete.

The plastic waste is another massive drawback to dispose [8]. The plastic demand in market are

going to be high and disposing of land isn't on the market thus reprocess or recycle the plastic

waste .the maximum plastic waste is use in construction and dispose .

3. RESULTS AND DISCUSSION

Cubes ,Beams, and Cylinder were casted for the ratio mentioned in table 2.these sample were

then kept for curing for 14 and 28days .Each specimen were casted a three sample and vibration

or compaction done after the casting. The specimen was removed from moulds after 24hours

of casting. These samples were then kept for curing for 14 and 28 days. After 14 and 28 days

test for compressive strength test, spilt tensile strength test, flexural strength test. The specimen

was tested in compressive testing machine and flexural testing machine. After testing each

sample were calculated average value .these all valves mention in figure 5(a), 5(b), 5(c)

3.1. Compressive strength:

Compressive strength is tested in the compressive testing machine .Dimension of cubes moulds

is 150mm*150mm*150mm.

Total 30 samples of cubes were casted. Each specimen were casted a 3 sample for test.

Average value of each specimen was calculated after testing. Compressive strength was

measured by load/ Area.

Table3, shown the result of cubes using coated fibre ratio by replacement of cement at 0.5%,

1%, 1.5%, and 2%. When compressive strength of casted cubes samples of coated fibber ratio

for 14 and 28days compare with conventional concrete samples strength were almost increase

in different percentages but the maximum strength ware increase in 1.5%. Replacement of

cement with 1.5% replacement is found to be reasonable.

Spilt tensile strength is tested in compressive testing machine . Diamension of cylinder moulds

300*150mm[10]. The spilt tensile strenght of concrete 14 and 28 days results shown in table

4.Total 30 sample of cylinder was casted for 14 and 28 days curing periods for testing. The

strength of 14 dyas 20 to 22% percentages increase as comprasion of normal concrete and

28days strength increase[7] by[7] 23 to 25 % percentage. IS 5816:1999 use for calculation of

CONCLUSION

The following conclusion can be drawn from this research study;

• When results of use Bagasse ash coated PET fibres ratio concrete samples was compared with the results of

conventional concrete samples in terms of compressive strength test ,spilt tensile strength test ,flexural strength test,of

M40 grade for 14 and 28 days, it was observed that the compressive strength ,spilt tensile strength ,flexural strength

of concrete initially increase when was replaced by coated PET fibres with cement at 0%,0.5%,1%,1.5%,2% percents.

Strength is almost increase using coated fibres ratios as compare with conventional concrete.

• The optimum strength increase[6]was found[7] maximum at 1.5 %replacement of PET fibres

• A increase of 16.13% was found in the testing of compressive strength.

• A increase of 25% was found in the testing of spilt tensile strength.

• A increase of 31% was found in the testing of flexural strength

• The use of PET fibres in concrete reduces plastic waste and save environment.

• The PET fibbers is economical and ecofriendly [1].

• Replacement of PET fibres with cement is reducing the cost of construction and reduces the emission of CO2.

• Hence conclude that the most optimum percentage for use of coated PET fibre replacement with cement is 1.5%.
