Experimental Study on Properties of Concrete with Coconut Shells and Fly Ash

This work's primary goal is to assess the qualities of concrete that has been hardened and fresh using fly ash and coconut shell. These days, a lot of research is being done to identify substitute building materials because cement and other elements required to make concrete are becoming scarce. In this experimental inquiry, we consistently employed 30% fly ash as cement and 10% to 30% of shell of coconut as CA. Concrete covering fly ash and coconut shell was compared to conventional concrete, both in its fresh and hardened states, without any substitutions. Upon completion of this study, it was found that a rise in the proportion of coconut shell replacement would result in a notable decrease in workability. The highest workability is achieved in concrete that has 30% FA as binding cement and 10% CS as a CA. Additionally, it was shown that concrete containing 30% FA and 10% shell of coconut as coarser aggregate had the highest compressive potency and tensile parameter strength.
