Coconut shell powder exhibits admirable properties compared to other materials such as low cost, renewable, high specific strength to weight ratio, low density less abrasion to machine and environmental friendly. Therefore the suitability of coconut fibre reinforced concrete with super plasticizer is studied in comparison with different proportion of coconut fiber. The coconut fibres treated with gum and pozzolanic materials improved the mechanical properties of coconut fibre reinforced self-compacting concrete (CFRSCC) specimens to a greater extent. Mechanical and dynamic properties of coconut fibre reinforced concrete This study focused on the use of coconut fibre to achieve this feat. Fire outbreaks in buildings have been a major concern in the world today. 60, 2009, pp. Carbohydr Polym 79(4):832–838 CrossRef Google Scholar de Farias JGG, Cavalcante RC, Canabarro BR, Viana HM, Scholz S, Simão RA (2017) Surface lignin removal on coir fibers by plasma treatment for improved adhesion in thermoplastic starch composites. The ability to resist cracking and spalling were also enhanced. 10, 2011, pp. Mixing coconut shell powder with epoxy resin enhances its properties and creates a wide range of applications. Traditionally coconut coir fiber is only used for brooms, mats, ropes and tools of other household. [11] Al-Mansob, R. A., A. Ismail, M. A. Algorafi, M. H. Hafezi and M. S. Baghini (2013). In this paper, early research on the structure and properties of coir fibres has been critically reviewed. Each fibre material has its own distinctive properties. Three different soil samples were sourced and mixed with different percentage proportions of coconut fiber (0.1%, 0.3%, 0.5%, 0.7%, 0.9%, 1.0%, 1.2% and 1.5%). Chemically treated coir fibre reinforced specimens yielded better mechanical properties compared to the raw ones. The chemical softening recipe was optimized using Box-Behnken design of experiments as 40 % Na2S, 10 % NaOH and 6 % Na2CO3, which notably reduced the fineness (33 %) and flexural rigidity (74 %) and improved tensile property of coconut fibre. Hence coconut fibre can be a better alternative as construction materials. Hence it was concluded that the treatment of coconut fibre had shown improved strength characteristics of CFRSCC specimens. Chemical properties and mechanical properties of hardness, abrasion resistance, tensile strength, modulus and flexural indices also increased with carbonization temperature. The study comprises of comparative statement of properties of coconut fibre reinforced concrete with conventional concrete based on experiments performed in the laboratory.

Ramadurai published on 2019/12/18 download full … The integrity of concrete is usually questioned due to the fact that after these fire outbreaks the strength of the concrete is reduced considerably. 1. Coconut fibres were subjected to chemical treatment to obtain softer and finer fibres, suitable to blend with other finer fibre like jute. However, the addition of fibres adversely affected the compressive strength. M. Natural Resource Research & Development Centre, Thiruvananthapuram 695 583, India The choice for the right fibre is depending on the characteristics of the application. Jurnal Kejuruteraan 25: 25-31. 2074– 2079. The need for strength or break load, stretch, dimensions or fatigue life will be of influence on the right fibre choice. Coconut fibre is one of many fibres which can be used in concrete. Indian Journal of Fibre & Textile Research Vol. 7,11 – 13 Interestingly, the coconut trunk occupies a dominant volume of the coconut tree, but it has not been appropriately investigated. In addition to this mix, sea water replaced the conventional one in the mix and the structural characteristics were ascertained. In tensile test the composite made from HCL treated coconut coir and untreated coconut shell powder fibers. M-30 coconut fiber concrete showed fall in its properties when exposed to temperatures above 200C. Loss of weight due to acid, sulfate and chloride attackis 11 %, 8.15 % and 5.14 % respectively after exposure of 30 days. By adding the coconut fibre the workability was not achieved which was required. The fiber obtained from the dry outer covering of the coconut fiber is termed as “coir”. The use of coconut fibres will also lead to better management of these waste fibres. For coconut fibre, micro structural analysis (scanning electron microscopy) test was conducted in the laboratory to get a better understanding of the bonding behaviour of fibres. Compared to coir fiber, coconut trunk particles also naturally contain a high content of lignin and hemicellulose (). This fiber has the best toughness among all natural fibres. The coconut fibres treated with gum and pozzolanic materials improved the mechanical properties of coconut fibre reinforced self-compacting concrete (CFRSCC) specimens to a greater extent. With addition of this coconut fibers and ash component, there seems to be an optimistic increase in base strength properties of the mix and also a sound result when it comes … ISRN Mater Sci 2012:134683 Google Scholar. These coir fibres have the tendency to be used as reinforcement in low cost concrete structures particularly in earthquake regions because of their property of toughness and sturdiness. 44-49.
