In the quest to reduce the construction sector’s carbon footprint, researchers have turned to an unlikely ally: abaca fiber. A recent study published in the *E3S Web of Conferences* (translated as “Environmental Sciences and Sustainable Development Web of Conferences”) explores how this natural material can enhance the mechanical performance of concrete, offering a sustainable alternative to traditional reinforcement methods.
Led by Farizal Teuku, a doctoral candidate at the School of Engineering, Universitas Syiah Kuala, the research investigates the potential of abaca fiber (Musa textilis) to improve the compressive strength of concrete. With carbon emissions from cement-based concrete posing a significant challenge to sustainable development goals, the study’s findings could pave the way for more eco-friendly construction practices.
The research focuses on two dosages of abaca fiber: 0.35% and 0.70% by cement weight. Using a mix design without chemical admixtures and a fixed water-cement ratio of 0.45, the team conducted compressive strength tests on standard cylindrical specimens at 7 and 28 days. The results were promising. Both fiber-reinforced mixes showed improved compressive strength compared to the control. Notably, the 0.70% dosage achieved the highest strength, with a 15.02% increase over the control, while the 0.35% dosage provided a moderate gain of 6.03% with better mixing stability.
“These findings enrich empirical data on natural fiber-reinforced concrete and affirm the strategic role of locally sourced biomaterials in low-carbon construction,” Teuku explained. The greater strength gain at 28 days suggests enhanced fiber bridging during hydration, a critical factor in the long-term performance of concrete structures.
The implications for the energy sector are significant. As the world shifts towards sustainable energy solutions, the demand for eco-friendly construction materials is on the rise. Abaca fiber, with its high tensile strength, biodegradability, and availability in tropical regions, offers a viable alternative to traditional reinforcement materials. By incorporating locally sourced biomaterials, the construction industry can reduce its carbon footprint and support circular economy principles, aligning with the targets of Sustainable Development Goals (SDGs) 11 and 12.
This research not only highlights the potential of abaca fiber in enhancing the mechanical performance of concrete but also underscores the importance of innovative solutions in achieving sustainable development goals. As the energy sector continues to evolve, the integration of natural materials like abaca fiber could play a pivotal role in shaping the future of construction.
The study, published in the *E3S Web of Conferences*, serves as a testament to the ongoing efforts to merge scientific research with practical applications, driving the industry towards a more sustainable and resilient future.
