本研究は、ポルトランドセメントの代替としてパーム油燃料灰（POFA）とジュート繊維（JF）をコンクリートに混入し、強度と環境効率を評価。最適配合（POFA 12.66%、JF 0.244%）では86%の適合率を達成し、機械的性能向上と炭素排出低減を両立。持続可能な建設材料の実現可能性を示した。
English
This study investigates the combined use of palm oil fuel ash (POFA) and jute fiber (JF) in concrete to reduce cement-related carbon emissions. Experimental tests show that 0.10% JF with 10% POFA improves mechanical strength by up to 26%, while 25% POFA minimizes embodied carbon. An optimized mix (12.66% POFA, 0.244% JF) achieves an 86% desirability index, balancing performance and sustainability. The findings support the development of eco-efficient concrete using agro-waste and natural fibers.

📄 Abstract（原文）
The extensive use of Portland cement significantly contributes to global carbon emissions, demanding sustainable alternatives in construction. This study investigates the combined influence of palm oil fuel ash (POFA), a supplementary cementitious material, and jute fiber (JF), a natural reinforcement, on the performance and eco-efficiency of concrete. Experimental tests assessed compressive, tensile, flexural strengths, modulus of elasticity, and ultrasonic pulse velocity, alongside embodied carbon and eco-strength efficiency. Response Surface Methodology (RSM) was employed to model responses, while multi-objective optimization determined the ideal mix proportions. Results reveal that incorporating 0.10% JF with 10% POFA enhances mechanical performance by up to 26%, while 25% POFA substitution yields the lowest embodied carbon. The optimized blend (12.66% POFA and 0.244% JF) achieved an 86% desirability index, balancing strength and sustainability. These findings provide new evidence that the integration of agro-waste ash with natural fibers, supported by statistical optimization, offers a viable pathway for producing eco-efficient, high-performance concrete, thereby advancing sustainable construction practices. Future work may extend these findings through microstructural and durability assessment to further validate the long-term sustainability of POFA-JF concrete.
