Abstract: Recently, there has been a growing interest in utilizing agro-waste as a source of supplementary cementitious material (SCMs) in construction. - SCMs are commonly used as partial cement substitutes to enhance material performance and reduce the environmental impact of construction. However, their reliance on industrial by-products raises concerns about future availability, emphasizing the need for sustainable alternatives. Agro-waste with pozzolanic properties offers a promising solution by repurposing agricultural residues into effective binders. One such agro-waste is date palm fronds ash (DPFA), evaluated as an additive in cement mortar at replacement levels of 10%, 20%, and 30% by weight. Key parameters studied included flowability, wet density, air content, compressive strength, and flexural strength. Results showed that DPFA reduced flowability and wet density while increasing air content. The optimal performance was achieved at 10% replacement, balancing strength and sustainability, while up to 30% replacement provided acceptable strength for various applications. Although flexural strength decreased compared to the control, higher DPFA levels showed improvement over time, demonstrating long-term potential. From a sustainability perspective, incorporating DPFA addresses agro-waste disposal while reducing the carbon footprint of cement production by lowering clinker demand. This aligns with global efforts to adopt eco-friendly practices, highlighting DPFA’s role in advancing sustainable and resource-efficient construction solutions.
