Experimental Study on the Mechanical Behavior of Fiber-Reinforced Coconut Shell Concrete

Abstract

Results in a substantial accumulation of agricultural waste, including coconut shells.
Incorporating CS as a replacement for traditional coarse aggregates not only helps reduce environmental impact but also lowers the overall cost of concrete production. Previous studies have demonstrated that coconut shell can effectively replace crushed stone aggregates in the production of eco-friendly lightweight concrete, commonly referred to as Coconut Shell Concrete (CSC).
The present study explores two mix types: one with coconut shell as the sole coarse aggregate (CSF) and another with a combination of coconut shell and conventional aggregates (CSP). In both mixes, cement was partially replaced with Class F fly ash at levels of 0%, 10%, 20%, and 30% by weight. The experimental results revealed that the mix containing 10% fly ash exhibited the highest compressive and tensile strength among all proportions, highlighting its potential as a sustainable and efficient concrete material.
