Investigate the Behavior of Concrete Properties with Organic Fiber

Abstract

The usages of natural fibers like jute, coconut coir and sugarcane in construction are widely used in building materials engineering to reinforce concrete's strength which is locally accessible and less expensive in Bangladesh. The concrete behavior such as compressive strength and workability of Fiber Reinforced Concrete (FRC) were experimentally investigated. The objective was to compare the outcomes of the FRC with regular concrete. To add fiber and experiment with fiber percentages while observing the effects of the previously specified factors, standard-sized cylinders were created. The mix proportion of concrete was 1:1.5:3 and the water-cement ratio were 0.55. The fiber used in concrete was 0 %, 0.5 %, 1.0 %, and 1.5 % by volume of concrete. As the percentage of fiber was gradually increased, the slump values dropped and sugarcane bagasse fiber showed more workability for the slump value than Jute or Coconut fiber. By mixing with fiber the mechanical property was improved. Those FRC specimens achieved increased compressive strength for 1% of fiber compared with regular concrete but didn’t show any similar pattern. More specimens or admixtures were required for clear observation and results. Natural fiber can be an effective way to increase the mechanical property of concrete. This will look at ways to improve concrete's properties as well as techniques to reduce the usage of polymer, which is terrible for the environment, and reuse fiber waste.
