Abstract:

Sustainability is a widely acknowledged concept in modern day construction scenario. Although the construction industry is transforming in a substantial way in terms of the material used and the equipment used, the construction cost has risen steeply along with the worse impact on the environment due to this it has resulted in the acceptance of method like the use of natural fiber for example Coconut fibre for improving the strength of concrete. Coconut fiber is easily and widely available in abundance, which makes it fairly sustainable as form of reinforcement material in concrete. The use of

Abstract:

Polymeric materials reinforced with synthetic fibres such as glass provide advantage of high stiffness and high strength to weight ratio. Despite these advantages, the widespread use of synthetic fibre-reinforced polymer composite has a tendency to decline because of their high-initial cost and most importantly their adverse environmental impact. In this work, four different composites are prepared with untreated coconut fibres, NaOH mercerized coconut fibres, KOH mercerized coconut fibres and CSM glass fibres. A lot of studies are done earlier on NaOH mercerized coconut fibre composites. But,

Abstract:

Natural fibre waste is a material with high material resistance, including fibres derived from coconut fruit. Coconut fruit waste is frequently underutilised and can contribute to environmental pollution if not handled correctly. This study's objective is to convert waste from coconuts into fibres, incorporate them into composite mixtures, and produce robust materials. Using coconut fibre presents a significant advantage in that it is easily biodegradable, reducing environmental pollution.

Abstract:

Fire outbreaks in buildings have been a major concern in the world today. The integrity of concrete is usually questioned due to the fact that after these fire outbreaks the strength of the concrete is reduced considerably. Various methods have been adopted to improve the fire resistance property of concrete. This study focused on the use of coconut fibre to achieve this feat. In this study, varying percentages of treated and untreated coconut fibres were incorporated into concrete and the compressive strength was tested for both before heating and after heating.

In the last few years, there is emerging attention in using Lightweight Foamed Concrete (LFC) as a lightweight non-structural and semi-structural element in buildings to take advantage of its excellent insulation properties. Though, LFC has been noticed to have some disadvantages: considerable brittleness; results in low compressive and flexural strength, poor fracture toughness, poor resistance to crack propagation and low impact strength. Coconut fibre obtained from coconut husk, belonging to the family of palm fibres, is agricultural waste products obtained in the processing of coconut oil.

Abstract:

Purpose This study aims to investigate the optimum proportion of coconut fibre and cement suitable for rammed earth wall construction. Coconut fibres and cement can be easily incorporated into the soil mixture which adds strength and durability to the wall. This paper highlights the salient observations from a systematic investigation on the effect of coconut fibre on the performance of stabilized rammed earth blocks. Design/methodology/approach Stabilization of soil was done by adding Ordinary Portland Cement (2.5, 5.0, 7.5 and 10.0 per cent by weight of soil), whereas coconut fibre in length

Finishing of coconut wood use the polyurethane, melamine formaldehyde and ultran vernis with the spraying 1 times and 2 times. Research target for the change of performance of colour and fibre of coconut wood more interesting. Result of research indicate that the use of substance of finishing polyurethane, melamine formaldehyde and ultran vernis can change the colour and fibre. Before coconut wood done finishing have the black chocolate colour and fibre pattern rather dark. After doing finishing colour become the squeezing chocolate, fibre pattern rather look and flatten.Keywords: coconut wood

Abstract:

Now a days, the natural fibres from renewable natural resources offer the potential to act as a reinforcing material for polymer composites alternative to the use of glass, carbon and other man made fibres. Among various fibres, coir is most widely used natural fiber due to its advantages like easy availability, low density, low production cost and satisfactory mechanical properties. For a composite material, its mechanical behavior depends on many factors such as fiber content, orientation, types, length etc. Natural fibre composites NFC are gaining interest in manufacturing because they addr

Abstract:

A bacterial consortium developed on coconut husk leachates could ret coconut husk steeped for retting in rap water in a period of three months. The quality of the coir fibre obtained was comparable to traditionally retted fibre. The consortia could also bestow a greater degree of softness to the mechanically extracted coir fibre. Coir extraction can therefore be practiced by supplying the consortia for retting of husk for production of fibre and enhance the commercial utilization of the husk in coconut growing regions of Asia.

Self-Compacting Concrete (SCC) has revolutionized the construction industry with its superior flowability, workability, and ability to consolidate under its own weight without the need for mechanical vibration. However, the brittleness and cracking susceptibility of traditional SCC remain significant concerns, especially in applications requiring enhanced durability and structural integrity. To address these challenges, the incorporation of natural fibres such as coconut fibres into SCC has emerged as a promising solution.

Abstract Concrete, a structural material in buildings is made of aggregate, which is a dense, chemically inert material, cement, and water. Concrete’s production, use, and environmental impact are complicated, influenced in part by the direct effects of infrastructure and buildings as well as CO2 emissions. Cement, a key ingredient with its own negative social and environmental effects, is a significant part of what makes concrete. To reduce CO2 emissions, it is important to substitute another material for cement. Slag is one of these alternative materials. It is a byproduct of steel factories
