Sažetak
The quest for sustainable construction materials is driving the exploration of agricultural by-products as eco-friendly alternatives in concrete production. This study investigates the combined effect of banana fibre (BF) and banana leaf ash (BLA), derived from the Musa spp. plant, on the mechanical and durability performance of concrete. BFs at percentages of 0,25 %, 0,50 %, and 0,70 % were used as natural reinforcement to improve tensile characteristics. BLA, which is rich in silica and other pozzolanic compounds, was utilized as a partial cement replacement at varying percentages of 5 %, 10 %, 15 %, and 20 %. Experimental analysis included slump, compressive strength, split tensile strength, and flexural strength tests over different curing periods. An optimal combination of BF and BLA enhanced the tensile properties and improved resistance to environmental degradation without significantly compromising compressive strength. The findings suggest that incorporating banana waste derivatives enhances concrete performance and contributes to a more sustainable and circular construction economy.
