Cement concrete serves as the primary building material for most of a country's infrastructure. A significant portion of the concrete's overall volume is made up of the aggregate. However, the ongoing use of granite rock for coarse aggregate increases the demand for natural resources by future generations. Because of its huge carbon footprint, the cement sector contributes significantly to global warming. A more cost-effective and sustainable growth of the building industry may arise from the appropriate reduction of cement usage in concrete without compromising its primary properties. In this work, lightweight coconut shell concrete is created by replacing crushed granite aggregate in concrete with coconut shell, an agricultural waste. The POFA is a pozzolanic waste product from the palm oil industry. Between 5% and 15% POFA replacements were added to the cement. The findings demonstrated that a 10% POFA replacement enhanced the lightweight coconut shell concrete's fresh, mechanical and durability properties. In the building industry, using coconut shell and POFA together in concrete would be the most eco-friendly option.
