I. INTRODUCTION
A. Introduction
Although the market for fiber-reinforced concrete is still small compared to total concrete production, the annual global consumption of fibers used in concrete is 300,000 tons. Concrete that contains cement, water, aggregates and discontinuous discrete fibers is called fiber reinforced concrete. The fibers can be in the form of banana fiber, steel fiber, glass fiber, natural fiber, synthetic fiber etc. The fibers are used to reduce shrinkage cracking. The main role of the fibers is to join the cracks that develop in the concrete and increase the ductility of the concrete elements, improving the behavior after the cracking of the concrete. It increases the resistance to the impact load, controls the cracking by plastic shrinkage and cracking by shrinkage by drying and decreases the permeability of the concrete matrix and, therefore, reduces water bleeding. Fiber improves the strength of concrete. Hardness is the ability of a material to absorb the energy and deform plastically without fracturing. It can also be defined as resistance to fracture of a material when stressed. Fibers offer several advantages of steel bars and wire mesh to reduce shrinkage cracks. The fibers are less sensitive to corrosion than reinforcing steel bars and the fibers can reduce the labor cost of placing the bars and the wire mesh. Banana fiber reinforced concrete have been used for making roof tiles, corrugated sheets, pipes, tanks etc. Concrete made with Portland cement has certain characteristics; it is strong in compression but weak in tension and tends to be brittle. The weakness in tension can be overcome by the use of conventional steel bar reinforcement and to some extent by the inclusion of a sufficient volume of certain fibers. The use of fibers also alters the behavior of the fiber-matrix composite after it has cracked. The aim of this research is to experiment on the use of banana fibers as an enhancement of concrete. This research describes experimental studies on the use of banana fiber to enhance the strength and applications of concrete. These natural fibers have excellent physical and mechanical properties and can be used more effectively. They are economical without chemicals. The addition of banana fibers significantly improved many of the engineering properties of the concrete compressive strength, tensile strength and flexural strength. Concrete reinforced with banana fiber has been used for shingles, corrugated sheets, pipes, silos and tanks. Concrete made with Portland cement has some characteristics; It is strong in compression but in weak tension and tends to be fragile. The weakness in tension can be overcome by the use of steel bar reinforcement and, by including a sufficient volume of certain fibers. The use of fibers also alters the behavior of the fiber-matrix composite after it has cracked. The objective of this research is to experiment on the use of banana fibers as an improvement in concrete. This research describes experimental studies on the use of banana fiber to increase the strength and applications of concrete. These natural fibers have excellent physical and mechanical properties and can be used more effectively.
They are economical with no chemicals. The addition of banana fibers majorly improved many of the engineering properties of concrete compression strength, tensile strength and flexural strength.
B. Objective Of The Study
Objectives of the present study are presented as follows:
C. Purpose Of The Study
Over 10 million hectares of Banana plantation, with an average of 1500 plants per hectare, exist in more than 160 countries globally, creating tons of banana waste, which have been left over to decompose, emitting a huge amount of methane gas and carbon dioxide. These emissions have a negative impact on the environment, which increases global warming every year. Every ton of banana waste emits, on average, a half-ton of carbon dioxide per year.
This kind of waste has a greater chance of being utilized for different application in construction and building materials. The addition of banana fibres can significantly improve many of the engineering properties of the concrete notably compressive strength, tensile strength and flexural strength. They are economical (zero cost), with no chemicals environmentally friendly and sustainable alternatives from unutilized waste (i.e., banana fibers).

In this study on analyzing the effect of various diameter of banana fibers chosen randomly within the range of variation of diameter starting from 0.08mm to 0.32m. Based on a class interval of 0.029 mm, which establishes that the standard deviation has decreased with an increase of diameter of the fibers meaning that courser fibers were more regular in nature. The majority of the fibers, as evident from come in the diameter range of 0.17mm to 0.19mm. Hence such fibers were chosen for tensile testing and it was revealed that strain rates played on important role in the nature of the stress strain curve, the strength of the fibers and the nature of failure.

Study of Literature Review for material requirements and observation. Procurement of the material to be used in preparation of the concrete mix i.e. Cement (43 OPC grade), Coarse Aggregate (locally available), Fine Aggregate (locally available) and Banana fiber was done. Number of tests were conducted on the cement and aggregates.Casting of test sample blocks.compression Test Blocks (150x150x150) mm Weighing of material was done followed by manual mixing and finally 9 cubes (3+3+3) were casted each for conventional concrete (0%),0.5%,1%,1.5% and 2% to get the result for 7days,14 days and 28day.Split-Tensile Test Cylinder Weighing of material was done followed by manual mixing and finally 8 Cylinders (2+2) are casted each for conventional concrete (0%) ,0.5%,1% and 2% to get the result for 7days and 28day.

From the result obtained, tables were made to get the averages from the two values and finally Bar Graphs for pictorial comparison were obtained.
A. Materials
The materials used commonly available Coarse aggregates, fine aggregates, type I Ordinary Portland Cement (OPC), and banana fibers. The fiber is “stick-like” with an embossed surface to create deformations that provide mechanical anchorage. The lengths of the banana fibers were 50 mm cut from full-length fibers.
Banana fibers are generally lignocelluloses material, consisting of helically wound cellulose micro- fibrils in amorphous matrix of lignin and hemicelluloses. The cellulose content serves as a deciding factor for mechanical properties along with micro fibril-angle. A high cellulose content and low micro-fibril angle impart desirable mechanical properties for banana fibers. Lignin are associated with the hemicelluloses and play an important role in the natural decay resistance of the lignocelluloses materials.
2. Cement
A cement is a binder, a substance used in construction that sets, hardens and adheres to other materials, binding them together. Cement is seldom used solely, but is used to bind sand and gravel (aggregate) together. OPC of 43 grades available in local market was used. Cement must develop the appropriate strength. It must represent the appropriate rheological behavior. Generally same types of cements have quite different rheological and strength characteristics, particularly when used in combination with admixtures and supplementary cementing materials.
3. Coarse Aggregate
As coarse aggregates in concrete occupy 35 to70% of the volume of the concrete. It may be proper to categories the properties into two groups: exterior features (maximum size, particle shape, textures) and interior quality (strength, density, porosity, hardness, elastic modulus, chemical mineral composition etc.). Smaller sized aggregates produce higher concrete strength. Particle shape and texture affect the workability of fresh concrete. The transition zone between cement paste and coarse aggregates, rather than the properties of the coarse aggregates itself. Locally available coarse aggregate having the maximum size of 20 mm and FM of 7.04 is used. The specific gravity of coarse aggregate that was taken was 2.7.
4. Fine Aggregate
Fine aggregate normally consists of natural, crushed, or manufactured sand. Natural sand is the usual component for normal weight concrete. In some cases, manufactured lightweight particles used for lightweight concrete and mortar. The maximum grain size and size distribution of the fine aggregate depends on the type of product being made. The sand sieved through 4.75mm sieve and retained on 1.18 mm sieve is used having specific gravity of 2.6 a FM of 2.7.
5. Water
Water is an important ingredient of concrete as it actually participates in the chemical reaction with cement. Water cement ratio used in the mix is 0.45 for BFRC.
B. Test Performed
a. Fineness Test Of Cement
Objective: Determination of fineness of cement by dry sieving.
Reference: IS 4031 (Part-1):1988.
Fineness Test on Cement is carried out to check proper grinding of cement. Fineness of cement particles may be determined either by sieve test. In sieve test, the cement weighing 100 gm is taken and it is continuously passed for 15 minutes through standard BIS sieve no. 9. The residue is then weighed and this weight should not be more than 10 per cent of original weight. When the results differ by more than 1 percent absolute, carry out a third sieving and calculate the mean of the three values.
c. Initial And Final Setting Time Of Cement
Objective: Determination of initial and final setting time of cement and determine whether the values satisfy IS standards.
Reference: IS 4031 (Part-5):1988
Cement is widely used material in building construction for making cement mortar and concrete. As we know that cement start hydrates when it is mixed with water. In presence of water, cement has a property to achieve strength and get hardened within a short period. So its mandate to place the cement in position without losing its plasticity. To achieve this, the setting time of cement is calculated. Initial Setting time of Cement:- The time to which cement can be moulded in any desired shape without losing it strength is called Initial setting time of cement.
Final setting time of Cement:- The time at which cement completely loses its plasticity and became hard is a final setting time of cement.
2. Tests Performed On Aggregates
Objective: To determine fineness modulus and grade of fine and coarse aggregate
Reference: IS: 383-1970.
a. Fineness Modulus Of Coarse Aggregates
Fineness modulus of coarse aggregates represents the average size of the particles in the coarse aggregate by an index number. It is calculated by performing sieve analysis with standard sieves.The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fine aggregate. Higher the aggregate size higher the Fineness modulus hence fineness modulus of coarse aggregate is higher than fine aggregate. Coarse aggregate means the aggregate which is retained on 4.75mm sieve when it is sieved through 4.75mm. To find fineness modulus of coarse aggregate we need sieve sizes of 80mm, 40mm, 20mm,10mm, 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm.Fineness modulus is the number at which the average size of particle is known when we counted from lower order sieve size to higher order sieve. So, in the calculation of coarse aggregate we need all sizes of sieve.
b. Fineness Modulus Of Fine Aggregates
Fineness modulus of fine aggregate is an index number which represents the mean size of the particles in fine aggregate. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fine aggregate.Fine aggregate means the aggregate which passes through 4.75mm sieve. To find the fineness modulus of fine aggregate we need sieve sizes of 4.75mm, 2.36mm,1.18mm,0.6mm,0.3mm and 0.15mm.Fineness modulus of finer aggregate is lower than fineness modulus of coarse aggregate.
2. Specific Gravity Of Fine Aggregate
Objective: To determine specific gravity of fine aggregate.
Reference: IS: 2386 (Part-3)-1963.
Fine aggregate is used in many fields in sites for many purposes.So the determination of specific gravity of fine aggregate is very essential. Specific gravity of fine aggregate can be defined as the ratio of the weight of given volume of coarse aggregate to the weight of given volume of distilled water.Clean the pycnometer, dry it, Find the weight of the pycnometer. Take about 200gm of coarse aggregate sample in the pycnometer.Weight the pycnometer, Note the weight W2 Fill the remaining part of pycnometer with distilled water and weight W3 Empty the pycnometer and clean it and fill it with distilled water.Note the weight W4.
C. Test Performed On Concrete
Objective: To determine the workability of freshly mixed concrete by the use of slump test.
Reference: IS: 7320-1974, IS: 1199-1959, SP: 23-1982.
Concrete slump test is to determine the workability or consistency of concrete mix prepared at the laboratory or the construction site during the progress of the work. Concrete slump test is carried out from batch to batch to check the uniform quality of concrete during construction.
The slump test is the most simple workability test for concrete, involves low cost and provides immediate results. Due to this fact, it has been widely used for workability tests since 1922. Generally concrete slump value is used to find the workability, which indicates water-cement ratio, but there are various factors including properties of materials, mixing methods, dosage, admixtures etc. also affect the concrete slump value.
2. Compressive Strength Test
Objective: To determine the cube strength of the concrete of given properties.
Reference: IS: 516 - 1959, IS: 1199-1959, SP: 23-1982, IS: 10086-1982.
To calculate the compressive strength of concrete cubes the universal testing machine (UTM) having capacity of 300 tonne was used. In this test the strength obtained in tonne. The measured compressive strength of the specimen shall be calculated by dividing the maximum load applied to the specimen during the test by the cross sectional area calculated from mean dimensions of the section and shall be expressed to the nearest N/mm2 Out of many test applied to the concrete, this is the utmost important which gives an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not. For cube test two types of specimens either cubes of 15 cm X 15 cm X 15 cm or 10cm X 10 cm x 10 cm depending upon the size of aggregate are used. For most of the works cubical moulds of size 15 cm x 15cm x 15 cm are commonly used. These specimens are tested by compression testing machine after 7 days curing, 28 days curing. Load should be applied gradually at the rate of 140 kg/cm2 per minute till the Specimens fails. Load at the failure divided by area of specimen gives the compressive strength of concrete. Calculations
3. Split Tensile Strength Test
Objective: To determine splitting tensile strength of cylindrical concrete specimens.
Reference: IS: 5816 - 1999, IS: 1199-1959, SP: 23-1982, IS: 10086-1982.
As we know that the concrete is weak in tension.Tensile strength is one of the basic and important properties of the concrete. The concrete is not usually expected to resist the direct tension because of its low tensile strength and brittle nature. However, the determination of tensile strength of concrete is necessary to determine the load at which the concrete members may crack. The cracking is a form of tension failure. The usefulness of the splitting cube test for assessing the tensile strength of concrete in the laboratory is widely accepted and the usefulness of the above test for control purposes in the field is under investigation. The standard has been prepared with a view to unifying the testing procedure for this type of test for tensile strength of concrete. The load at which splitting of specimen takes place shall then be recorded. The universal testing machine (UTM) having capacity of 150tonne was used for The splitting tensile strength of the concrete cylinders.Calculations:The split tensile strength of the specimen calculated from the following formula

The main objective of this study is to analyze the performance of addition of commercially available Banana fibers as an additive in cementitious materials to improve the mechanical properties of conventional concrete and to enhance the flexibility to resist cracking and spalling of concrete structures. The addition of banana fibers considerably increased the strength characteristics of concrete, compressive strength, tensile strength and flexural strength.The compressive strength of concrete has increased up to 0.5% addition of banana fibre and has shown decrement in the compressive strength that percentage.The compressive strength obtained at 0.5% fiber content is 37.77 N/mm2 which is 13.59% higher than the reference conventional concrete strength. A reduction in compressive strength is attributed to increase in porosity of the concrete matrix as a result of the addition of fibres, creating large contents of pores and microcracks at the matrix-fibre interface. Furthermore, reduction in compressive strength with increasing fibre content is likely to be associated with the effect of fibres on Interfacial Transition Zones (ITZs) and voids in concrete. It is expected that the more the amount of fibres, the more the ITZs will be created in concrete, which in turn negatively affects the compressive strength. The maximum split tensile strength attained at 0.5% fiber content is 3.24 N/mm2, which is 7.71% higher than the reference conventional concrete strength .hat addition of fibres had a signi?cant improvement in tensile strength because they slowed down crack propagation, thereby enhancing mechanical strength of concrete.A drop in tensile strength of BFRC beyond 1% of fibre content can be attributed to excessive amount of ?bre content in the concrete, which end up having an adverse effect on the strength of concrete as was similarly observed for compressive strength. The maximum flexural strength obtained at 0.5% fiber content is 4.08 N/mm2, which is 7.36% higher than the reference conventional concrete strength .Addition of banana fibres generally did not greatly contribute to flexural strength of concrete but had a marginal impact only when shorter fibres were used at lower fibre dosages. Contrastingly, the flexural strength of all BFRC mixes containing longer fibres decreased with increasing fibre content.
