In the bustling world of construction materials, a groundbreaking study led by Artyom Grigoryan, a researcher at the National University of Architecture and Construction of Armenia, has shed new light on the potential of basalt fibers to revolutionize cement mortar. The findings, published in the Journal of Architectural and Engineering Research, reveal that incorporating basalt fibers into cement mortar can significantly enhance its mechanical properties, paving the way for stronger, more durable structures.
Basalt fibers, derived from basalt rocks, are known for their high strength and stability, even in harsh environments. Grigoryan’s research delves into the impact of basalt fiber (BF) content on the mechanical properties of cement mortars, uncovering some compelling results. The optimal fiber concentration, determined through rigorous experimentation, was found to be 3.3 kg per 1 cubic meter of the mixture. This specific concentration yielded impressive results, with flexural strengths increasing by 3.7-16.2% for mixtures prepared with river sand and 9.1-16.8% for those prepared with lithoidal sand. Compressive strengths also saw notable improvements, rising by 3.1-13.7% with river sand and 5.9-12.4% with lithoidal sand.
The implications of these findings are vast, particularly for the energy sector, where the durability and strength of construction materials are paramount. “The use of basalt fibers in cement mortar can lead to more robust and long-lasting structures, which is crucial for infrastructure projects in the energy sector,” Grigoryan explains. “This innovation not only enhances the mechanical properties of the mortar but also contributes to sustainability by utilizing environmentally benign materials.”
The study’s focus on both river and lithoidal sands highlights the versatility of basalt fibers in different environmental conditions. This adaptability is a significant advantage for the construction industry, as it allows for the use of locally available materials, reducing transportation costs and environmental impact. “The ability to use abundant local sands, such as lithoidal light and river sands, makes this innovation particularly relevant for regions with limited access to high-quality construction materials,” Grigoryan notes.
The research also underscores the importance of fiber length in achieving optimal results. The study utilized basalt fibers up to 12 mm in length, demonstrating that longer fibers can contribute to enhanced compressive and bending strengths. This finding opens up new avenues for material science and engineering, encouraging further exploration into the optimal fiber lengths and configurations for various construction applications.
As the construction industry continues to evolve, the integration of basalt fibers into cement mortar represents a significant step forward. The enhanced mechanical properties and environmental benefits make this innovation a game-changer for the energy sector, where the durability and longevity of structures are critical. With the findings published in the Journal of Architectural and Engineering Research, the construction industry now has a roadmap for leveraging basalt fibers to build stronger, more sustainable structures.
