Materials Testing of Chicken Eggshells Powder & Coconut Fibers as a Replacement Material for Cement.

This research investigates the mechanical properties and performance of concrete using chicken eggshell powder (ESP) and coconut fibers (CF) as sustainable partial replacements for cement. Experimental batch testing, compressive strength evaluations, and flexural load analyses were conducted to determine the structural viability of agricultural and organic by-products in eco-friendly concrete mixes, offering a comparative performance baseline against traditional mixes for sustainable construction applications.
