In the quest for sustainable construction materials, a groundbreaking study has emerged, offering a promising solution to the industry’s environmental challenges. Researchers, led by Maryane Pipino Beraldo Almeida from the University of Western São Paulo (UNOESTE), have systematically reviewed the potential of basalt rock powder (BRP) as a viable component in cementitious materials. This innovative approach could not only enhance the mechanical properties of concrete and mortar but also significantly reduce waste and promote sustainability in the construction sector.
The study, published in the journal ‘Resources’ (translated from Portuguese), delves into the physical and chemical properties of BRP, highlighting its superior particle size distribution and compatibility with cementitious composites. “Basalt rock powder exhibits pozzolanic activity, which means it can react with calcium hydroxide in cement to form compounds that improve strength and durability,” explains Almeida. This characteristic makes BRP a valuable addition to construction materials, potentially transforming rock dust—a byproduct of quarrying—into a beneficial mineral resource.
The systematic review, conducted using prestigious databases such as Scopus, ScienceDirect, PubMed, and Web of Science, identified 17 peer-reviewed articles that met the inclusion criteria. These studies collectively demonstrate the positive impact of BRP on mechanical properties like compressive strength, flexural strength, and durability. By incorporating BRP into cementitious materials, the construction industry could reduce its reliance on natural resources, thereby mitigating environmental concerns and enhancing sustainability.
The commercial implications of this research are substantial, particularly for the energy sector. As the demand for sustainable construction materials grows, the adoption of BRP could lead to cost savings and improved efficiency. “Reusing rock dust as a raw material not only benefits the new material but also reduces waste volumes, contributing to a circular economy,” notes Almeida. This innovative solution aligns with global efforts to achieve net-zero emissions and promote sustainable development.
The study’s comprehensive search and rigorous screening process ensure a low risk of bias, reinforcing the credibility of its findings. As the construction industry continues to evolve, the integration of BRP into cementitious materials could pave the way for more sustainable and resilient infrastructure. This research not only highlights the potential of BRP but also underscores the importance of exploring alternative materials to address the current challenges in the construction sector.
