Performance Evaluation On Structural Behaviour Of Sisal Fibre Reinforced Concrete

All over the world, construction industries looking forward for the green materials to meet the structural integrity and sustainability in terms of arresting micro cracks in the concrete and also for a secondary reinforcement materials for addition in the concrete. Internal micro cracks in the concrete will reduce the longetivity of the structure and also it results in structural failure. The use of fibres in the concrete is currently used as a secondary reinforcement for strengthening the reinforced concrete members. To make the concrete as a sustainable material and to improve structural integrity in this research Sisal Fibre was used as a secondary reinforcement. Natural fiber such as sisal fibre, appears as an one of the good alternative since they are available in fibrous form and can be extracted from plant leaves at very low cost. In this work, effect of sisal fiber on the strength of concrete for M 25 grade has been studied by varying the percentage of fibers in concrete. Fiber content were varied by 0.05%, 0.10%, 0.15%, 0.20%, 0.25%, 0.30%, 0.35% and 0.40% by volume of concrete. Cubes, Cylinder and Prism were cast to evaluate the Strength Characteristics and to optimize dosage level of fibre in concrete. The reinforced concrete beam was cast by optimum dosage level of fibre to evaluate structural behavior of concrete such as Load deflection, Ductility factor and Stiffness. The result proven, there is significant improvement in structural behavior of Sisal Fibre added Reinforced Concrete when compared to control concrete.

Sisal Fibre Based Polymeric Composites

Nature origin fibres have drawn in extraordinary consideration from commercial and specialists for the use of polymer composites as a result of their ‘greener’ nature and commitment to maintainable practice. Different enterprises have moved towards reasonable innovation to work on the harmony between the climate and social and financial concerns. Innovative work has demonstrated that normal fibres have been effectively applied as fortifications in the composites business, for example, for transportation, inside segments, building, airplane.

Exploration of Tensile, Flexural and Chemical Inertness Properties of Sisal Fibre Reinforced Polymer Composites-Surface Analysis

Our Experimentation finds, reaction of fibre external analysis on tensile, flexural and chemical resistance properties were studied for sisal fibre reinforced composites. Fibre surface analysis has done to produce link between fibre and the matrix to improve the mechanical properties. Fibre surface analysis were done by boiled the sisal fibres in different % of NaOH and treated the fibres in different % of NaOH, treated in acetic acid and methanol. Polyester resin have used as the matrix for preparing the composites and these properties for Natural sisal fibre reinforced composites were also studied. From the results it was observed that 25% NaOH boiled sisal fibre reinforced composites have higher tensile, flexural properties than other composites. Natural sisal fibre composites show fewer properties than treated composites. Chemical inertness properties indicate that all sisal fibre reinforced composites are resistance to all chemical agents except carbon tetra chloride.

Evaluation of Mechanical Properties of Sisal and Bamboo Fibres Reinforced with Polymer Matrix Composites Prepared by Compression Moulding Process

Today’s modern, dynamic world would be impossible to imagine without the concept of composite material advancement. Various studies are being conducted in this area in order to reach the desired level. In terms of compatibility, natural fibre reinforced polymer-based composites and synthetic fibre composites are very similar. Because they are lightweight, nontoxic, and nonabrasive, they are very popular with consumers. They are also readily available and affordable. Composite materials made from natural fibre have superior mechanical properties compared to those made from synthetic fibre. As part of this research, an epoxy-based composite with bamboo and sisal fibre reinforcement is examined. Reinforced with epoxy resin, bamboo fibre and sisal fibre are used to make composite materials. The effect of adding bamboo fibre and sisal fibre in various weight percentages on the mechanical behaviour of composites is investigated.

Influence of Flax Fibre Hybridization on Mechanical Behaviour of Sisal Fibre-Polypropylene Composites Prepared with an Injection Moulding Machine

Due to their low weight, high specific strength, and low environmental impact, sisal fibre-polypropylene composites have gained popularity. However, the material has a low modulus and poor moisture resistance, among other shortcomings. This study investigated how flax fibre hybridization affects the physical parameters of sisal fibre-polypropylene composites. We used maleic anhydride-grafted polypropylene to improve compatibility between fibres and polypropylene. Adding flax fibres to polypropylene-silica composites resulted in increased tensile strength, flexibility, and impact strength, according to researchers. Water resistance was further improved by adding flax fibres. Tensile strength values of polypropylene-sisal fibre composites filled with 0, 5, 10, 15, and 20 wt% of flax fibres were 29.46, 30.56, 31.57, 33.12, and 34.64 MPa, respectively.

An Assessment of Flexural Improvement of Light Weight Concrete via Hybrid Fibres along with Sisal Fibres in Addition to Banana Fibres

Innate fibres, these days have become the topic of argument in the research field between different scientists to inculcate it in the formation of lightweight concrete mixture. This is due to a variety of rewards connected with natural fibres like recyclable, economical, availability in large quantity and its bio-degradability. Plenty of projects have been carried out in the production of natural fibre reinforced lightweight concrete. In this project, we would like to take the naturally existing fibre named sisal fibre and banana fibre as partial replacement material. The adding of natural fibre to the lightweight concrete will enhance the diverse strength parameters like flexural strength, compressive strength, and increase the ductile behaviour. In the current work, it is intended to explore the mechanical properties of lightweight concrete with substitution of sisal fibre and banana fibre for cement in different percentages. The compressive strength, flexural strength, deflection of the beam is calculated with the reflection of M30 concrete specimens. Totally 45 number of 500 x 100 x 100mm flexural member, 45 numbers of cubes and 45 numbers of cylinders are cast and tested. It is suggested that up to 1.5% substitution of sisal fibres and banana fibre with cement provide at M30 grade of concrete giveing the most beneficial increases of strength values. The assessment outcome indicated that the sisal fibres and banana fibre were efficient in improving the performance of lightweight concrete
