So, it can be a good alternative in construction area. Further work needs to be done in order to observe the effects of coconut fibre on concrete with various lengths and volume •
The fiber obtained from the dry outer covering of the coconut fiber is termed as "coir". This fiber has the best toughness among all natural fibres. 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. Some advantages of coir fibers include insect proof ...

01-08-2016· There is the recent development of producing concrete by use of coconut coir based fiber. Due to its less expensiveness, flexibility most of the coconut coir based concrete now getting much popular. By compare with other types of concrete coconut fiber-reinforced concrete is also strong and ideal for hard use. 11. To Create Brushes for home use
Reinforcement of concrete is necessary to enhance its engineering properties. For this study, coconut fibres were used as they are freely available in large quantities. The study comprises of comparative statement of properties of coconut fibre reinforced concrete with conventional concrete based on experiments performed in the laboratory. The use of coconut fibres will also lead to better ...
Both plain concrete and coconut fibre reinforced concrete cylinders of 100 mm × 200 mm were prepared. Ordinary Portland cement, sand, aggregate and coconut fibres were used. The mix design by weight was 1:4:4 for cement: aggregate: sand, respectively. The fibre length was 50 mm and fibre weight content was 0.4% of plain concrete.
The use of natural fibre as reinforcement in concrete (cement-sand matrix) has been comprehensively investigated in many countries (Rehsi, 1991; Atnaw et al., 2011) The natural fibre reinforced materials, which can be used in the production of building materials, are presently mainly those based on coconut, bamboo, cane, henequen and sisal fibres (Dawood and Ramli, 2011; Hamid et al., 2011).
The various mix proportions, the method of mixing, handling, and placing, and the properties of fresh and hardened natural fiber reinforced concretes are described in this report. The properties under research include flexural and compressive strength of the coconut fiber reinforced concrete (CRFC) at varying percentages (0.1%, 0.3%, 0.5% by weight of cement) of fiber.
23-07-2019· The fiber obtained from the dry outer covering of the coconut fiber is termed as "coir". This fiber has the best toughness among all natural fibres. 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.
31-10-2018· The data presented in this research show the results of the experimental study of acoustic behaviour of coconut fibre-reinforced concrete (CFRC). The CFRC was added in percentages of 0.25%, 0.5%, 0.75% and 1% of cement. The acoustic test was conducted to determine the amount of sound that can be absorbed by the fibre.

01-05-2012· Coconut fibres are used in plain concrete to improve its behaviour. Properties of coconut fibre reinforced concrete (CFRC) are investigated. Properties of plain concrete are taken as reference. Fibre contents of 1%, 2%, 3% and 5% and lengths of 2.5, 5 and 7.5 cm are considered. CFRC with a fibre length of 5 cm and a fibre content of 5% has the best properties.

Beyond 0.5% fibre, the compressive strength reduced. Concrete having coconut fibre that had been treated with water also exhibited the highest compressive strength of 28.71 N/mm². It is concluded that coconut fibres are a great material in improving the strength of concrete, even after it was exposed to a certain degree of elevated temperature.
Coconut fibre has been used to enhance concrete and mortar, and has proven to improve the toughness of the concrete and mortar in this research. Advantages of Fiber Reinforced Concrete Fibre reinforced concrete has high modulus of elasticity for effective long-term reinforcement, even in the hardened concrete.
Coconut and sisal-fibre reinforced concrete have been used for making roof tiles, corrugated sheets, pipes, silos and tanks (Agopyan, 1988). 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
