Description:DESCRIPTION:
Field of the invention:
[0001] The present disclosure generally relates to the technical field of a concrete compositions, and in specific relates to a composition of banana fibrous concrete that is sustainable, eco-friendly, economical and exhibits superior mechanical properties than any conventional concrete.
Background of the invention:
[0002] Construction technology has advanced through several investigations and experiments to enhance the strength and durability of concrete. Fibres used in concrete are mainly categorized into natural and artificial fibres. The sources of natural fibres are vegetables, animals, and mineral sources. The artificial fibres are produced from synthetic materials, steel, and natural polymers. Fibres exist in various forms, such as Cocosnucifera (coconut) fibre, Musa acuminate (banana) fibre, steel fibre, AR glass fibre, natural fibre, jute fibre, synthetic fibre, etc. Banana fibre offers resistance to suddenly applied loads, limits shrinkage cracking, decreases permeability, and hence ultimately decreases the bleeding of water.

[0003] A lot of researchers have shown remarkable interest in determining the behaviour of concrete using Nano-silica (NS) and its effect on its strength properties. Nano-silica fibres do have the amazing characteristic of acting as a cementitious pozzolonic additive, and on the other hand, they can also enhance the pore structure of concrete. Nano-silica can play a vital role in densifying the microstructure of the cement paste. In this particular investigation, the strength properties of concrete are investigated and determined experimentally by deploying various combinations of Nano-silica and banana fibres in concrete to attain a concrete with high characteristics compared with conventional concrete.

[0004] Fibrous concrete is a sort of reinforced concrete that contains aggregate, hydraulic cement, water, and discrete, discontinuous fibres [1:3]. Portland cement concrete is robust in compression but feeble in tension, and therefore it is brittle. The tension feebleness can be solved by including standard steel bar reinforcement and a sufficient volume of fibres. Fibres are widely classified as synthetic and natural fibres (NFs). Artificial fibres are composed of synthetic materials such as steel and synthetic polymers, whereas NFs are obtained from animals, plants, and minerals. The usage of NFs throws back to centuries-old cultures. For example, in Egypt, 3000 years ago, buildings were constructed by strengthening clay with straw. On the other hand, NFs have been widely used as appropriate reinforcement in a wide variety of industries since the second half of the 20th century.

[0005] Lately, a surge in public awareness has prompted the scientific community to seek environmentally friendly solutions and ways to slow the depletion of petroleum supplies. Thus, NFs are chosen over artificial fibres in matrix because of their multiple advantages, including lightweight, high specific strength, corrosion resistance, biodegradability, low cost, and broad availability [4:10]. On the other hand, NFs provide resistance to abruptly applied stresses and significantly reduce shrinkage cracking. Furthermore, the use of NFs in different building components of bearing and non-bearing structures has increased for both interior and exterior purposes. The global annual usage of fibres in concrete is 300,000 tons, even though the market for fibrous concrete is relatively modest in comparison to total concrete output.

[0006] When compared to synthetic fibres, the cost of NFs is extremely low; for instance, the cost of glass fibres is from $1200 to $1800 per ton, but NFs cost from $200 to $1,000. Not only does the banana plant yield delectable fruit, but it also produces textile fibre. Banana fibres (BFs) offer superior mechanical and physical qualities, allowing for increased productivity. Numerous engineering parameters of the concrete were greatly improved by adding BFs, especially regarding tensile strength, compressive strength, and flexural strength. Additionally, the resistance to spalling and cracking was improved. By adding BFs, concrete becomes more isotropic, homogeneous, and transitions from brittle to ductile failure. While reinforcing concrete with BFs retards crack propagation and thus improves its strength and impact characteristics, it also reduces workability, the inclusion of a superplasticizer helps with the possible issue of fibre tangling or balling.

[0007] Fibre-reinforced concrete (FRC) is a material created with Portland cement, aggregate, and separate discontinuous Traditional unreinforced concrete is brittle, with occasional tensile strength and strain capability. The addition of banana fibres to concrete makes it more homogenized and isotropic and transforms it from a brittle material into an additional ductile material. Conventional concrete includes varied microcracks that are quickly exaggerated below the applied stresses. These cracks are responsible for the low tensile strength, flexural strength, and impact resistance of concrete. Concrete strengthened with banana fibres impedes crack growth and so enhances its strength and impact characteristics; however, it'll also reduce its workability. The addition of super plasticizer (Sp) is useful to resolve the potential drawback of tangling or balling of fibres.

[0008] By addressing all the above-mentioned problems, there is a need for a composition of banana fibrous concrete that is sustainable, eco-friendly, economical, and exhibits superior mechanical properties than any conventional concrete. There is also a need for banana fibrous concrete that exhibits better compression strength than any conventional concrete. There is also a need for a composition of banana fibrous concrete that holds a good amount of moisture and does not lead to the development of crack length at lower loads when compared to conventional concrete. There is also a need for a composition of banana fibrous concrete, which has good ductile properties and exhibits better performance in tensile strength for M35 grade with or without adding Nano-silica. There is also a need for banana fibrous concrete that absorbs less water than any conventional concrete. There is also a need for banana fibrous concrete that contains materials that have a lower carbon footprint than other concrete mixtures. There is also a need for banana fibrous concrete that reduces the impact of carbon footprints on the environment, which leads to a lesser or no landfall of debris.
