Mechanical properties and sustainability aspects of coconut fiber modified concrete

Coir fiber has been examined for their suitability as reinforcement of concrete. Mechanical properties and sustainability aspects concrete composites were estimated after 7. 14, 28 days curing. Natural 0.46 0.62% by weight coir was added. Fibers analyzed means scanning electron microscope (SEM). Besides, an Eco-audit tool used to estimate energy carbon emission material, manufacturing, transportation, disposal phases. It found that fibers additions lowered the compressive strength compared plain However, failures exhibited good post-cracking behavior. The use vegetable affects positively life cycle material. results indicate there is a potential reduce between 9.15% 13.35% embodied 9.61% 13.94% CO2 during material production phase. These suggest could be useful from environmental view, although more studies regarding durability are needed.
