Dr. Abdul Razak Honnutagi coconut fibres has great potential in the production of lightweight concrete or normal concrete for use in the construction of concrete structures. Coconut fibre has been used to enhance concrete and mortar, and has proven to improve the toughness of the concrete and mortar (Gram, 1983, and Ramakrishna, et al., 2005). This study aimed toward analyzing the variation in strength of coconut fiber concrete at variable fiber contents and to establish it with that of conventional concrete. Anjuman-I-Islam’s Kalsekar Technical Campus Shaikh Mohd Shadab Mohd Shafi 12CE54 2 3, Sector – 16, Near Thana Naka, Khanda Gaon, Due to its less expensiveness, flexibility most of the coconut coir based concrete now getting much popular. Some types of fibres produce greater impact, abrasion and shatter resistance in concrete. Generally fibres do not increase the flexural strength of concrete, so it can not replace moment resisting or structural steel reinforcement. @��g��1��5�S�Ɉ�Mֿ���&�������y�*�&]��U�������o��I/����|����f�Y'���J�?����j?�E��2�Ҫ� Beyond 0.5% fibre, the compressive strength reduced.

The fiber obtained from the dry outer covering of the coconut fiber is termed as “coir”. 11. Fibers, which are at random dispersed throughout the foamed concrete, could overcome How to Make Hypertufa Pots - Duration: 2:43. Shaikh Shamsuddoha Mohd Umar 12CE56 • Then we again prepared 6/6 inches 3 cubes, in which coconut fiber was reinforced with concrete in 1%. • Lastly, we prepared 6/6 inches 3 cubes, in which coconut fiber was reinforced with concrete in 0.25%. The aim of this experimental study was to check whether there is a possibility of using the coconut fiber and chalk powder in addition to the other constituents of concrete and to study the strength properties. However, the problem of long term durability has not yet been solved. The results suggests that short coconut fibers are more effective in enhancing the performance of concrete The recommended threshold value of the fiber content that will benefit the long term durability of the concrete in all environments is 2.0 % The properties can increase or decrease depending upon fiber length and its content. However, the dosage of coconut fiber should be low, not exceeding 1.2% of the binder volume, due to the drawback of its natural degradation. This is a good explanation of the role coconut fibres play when incorporated into concrete. for the degree of They found that coconut fiber gave the best performance compared to sisal, jute and hibiscus cannebinus (Ramakrishna, 2005).
