Development of SCC Mix Using Jute and Coir as Additives

Coir fibres and jute fibres are natural materials that are abundantly available in tropical regions of our country. Waste generated by the industrial and agricultural processes has created disposal and management problems, which causes serious challenges for environmental conservation. A considerable amount of coir fibres and jute fibres remain in the environment as waste, so the utilization of these materials for construction is an important step to improve sustainability and eco-friendly construction. The current study deals with the addition of coir and jute fibres to concrete such as attain sustainable construction material without sacrificing the strength of concrete. To check its suitability, test for compressive strength, split tensile strength, flexure strength and water absorption test were performed. To ensure the suitability of coir fibres and jute fibres as ingredients of concrete the results obtained from above were compared with conventional concrete. Also, a comparative study of fibre reinforced concrete and self-compacting fibre reinforced concrete was carried out. The work was carried out by conducting tests on the raw materials to determine their properties and suitability as engineering material. Concrete mix designs were prepared using the IS method for an M30 grade concrete. The specimens were cast with percentage addition of 0.7 jute fibre and 0.3 coir fibre, 0.3 Jute fibre and 0.7 coir fibre and 0.5 Jute fibre and 0.5 coir fibre.
