In the quest for sustainable construction materials, hemp fibres are emerging as a game-changer, according to groundbreaking research led by Mariana Costa Laktim from the University of Naples Federico II. Published in the journal *Buildings* (which translates to *Edifici* in Italian), this study delves into the potential of hemp fibres to revolutionize the construction industry, offering a greener alternative to traditional materials.
Costa Laktim and her team conducted a comprehensive review of global research trends, focusing on hemp fibre treatments for inorganic matrices such as cement, lime, and geopolymers. Their findings highlight the significant improvements in mechanical performance and durability that can be achieved through various treatment methods.
“Hemp fibres offer a unique combination of high cellulose content, low density, and excellent tensile strength,” explains Costa Laktim. “When properly treated, these fibres can enhance the structural integrity of composites, making them a viable option for modern construction.”
The study critically assessed both chemical and physical treatment methods. Chemical treatments, such as alkaline, silane, acetylation, and alkyl ketene dimer (AKD), were found to improve fibre-matrix adhesion and mechanical strength. Physical treatments, including plasma and ozone modifications, enhanced surface roughness and interfacial bonding without compromising fibre integrity.
One of the most notable findings was the effectiveness of combined alkaline-AKD treatments, which increased compressive strength by approximately 30% and flexural strength by up to 25% compared to untreated composites. These improvements are significant for the construction industry, where strength and durability are paramount.
The research also underscores the need for standardized testing protocols and performance-based evaluations to facilitate the broader application of hemp-based composites. By integrating bibliometric mapping and keyword networks, the study provides a quantitative and engineering-oriented synthesis that highlights its original contribution to sustainable construction materials.
“This research is a stepping stone towards a more sustainable future in construction,” says Costa Laktim. “It not only highlights the potential of hemp fibres but also sets the stage for further innovation in the field.”
The implications for the energy sector are substantial. As the demand for sustainable and resilient structures grows, hemp-based composites could play a crucial role in reducing the carbon footprint of construction projects. This shift towards eco-friendly materials aligns with global efforts to combat climate change and promote sustainable development.
In conclusion, Costa Laktim’s research offers a compelling vision for the future of construction, where hemp fibres could become a cornerstone of sustainable and resilient structures. As the industry continues to evolve, the insights from this study will be invaluable in shaping the next generation of construction materials.
