In the quest to preserve historic structures while enhancing their durability, a groundbreaking study led by Analía Vázquez of the Escuela Técnica Superior de Edificación at the Universidad Politécnica de Madrid has shed new light on the potential of basalt fibres in hydraulic lime mortars. Published in ‘Anales de Edificación’ the study, which translates to ‘Annals of Construction’, delves into the mechanical behaviour of these mortars, both with and without basalt fibres, over extended periods.
The research, which builds upon previous findings, focuses on the long-term performance of basalt fibres in hydraulic lime mortars. Vázquez and her team conducted mechanical tests at 180 days to confirm the suitability of these fibres as a reinforcement material. The results were compelling: basalt fibres, particularly those measuring 12 mm in length, demonstrated a significant positive impact on the mechanical properties of the mortars. This finding is crucial for the energy sector, where the rehabilitation of historic structures often involves materials that must withstand harsh environmental conditions and maintain their integrity over time.
“The addition of basalt fibres to hydraulic lime mortars not only improves their mechanical behaviour but also ensures compatibility with traditional construction materials,” Vázquez stated. “This makes them an ideal choice for the rehabilitation of historic structures, which is a growing concern in the energy sector as we strive to preserve our heritage while enhancing energy efficiency.”
The study’s findings have far-reaching implications for the construction industry. By confirming the long-term benefits of basalt fibres, the research opens up new possibilities for the rehabilitation of historic structures. This could lead to more durable and energy-efficient buildings, reducing the need for frequent repairs and maintenance. Additionally, the use of basalt fibres in hydraulic lime mortars could contribute to the development of sustainable construction practices, aligning with the energy sector’s goals of reducing carbon footprints and promoting green building initiatives.
Vázquez’s research underscores the importance of continuous innovation in construction materials. The study’s focus on long-term performance and compatibility with traditional materials sets a new standard for the industry. As the demand for sustainable and durable construction solutions grows, the insights gained from this research could shape future developments in the field. By integrating basalt fibres into hydraulic lime mortars, the construction industry can enhance the durability and energy efficiency of historic structures, paving the way for a more sustainable future.
