In the quest for sustainable construction materials, a groundbreaking study led by Ahmed Minhajuddin from the Department of Civil Engineering at GITAM (Deemed to Be University) has unveiled the potential of waste granite powder (WGP) as a viable and cost-effective alternative to sand in concrete production. This research, published in the Journal of Materials Science: Materials in Engineering, offers a compelling solution to the global challenge of solid waste management, particularly in the granite processing industry.
The study delves into the physical and chemical properties of WGP, employing advanced techniques such as X-ray diffraction (XRD) and X-ray fluorescence (XRF) to understand its composition and behavior. The findings reveal that WGP can enhance the mechanical properties of concrete, including compressive strength and flexural strength, when used as a partial substitute for fine aggregate. “The results are quite promising,” says Minhajuddin. “We found that replacing up to 40% of the fine aggregate with WGP not only improves the concrete’s performance but also reduces the environmental impact of construction activities.”
The research goes beyond technical evaluations, conducting a detailed cost analysis to assess the economic feasibility of incorporating WGP into concrete production. The findings indicate that using WGP can lead to significant cost savings, making it an attractive option for the construction industry. “The economic benefits are substantial,” Minhajuddin explains. “By utilizing waste materials, we can reduce the cost of raw materials and contribute to a more sustainable construction sector.”
This study has far-reaching implications for the energy sector, where concrete is a fundamental material for infrastructure development. By adopting WGP as a sustainable alternative to sand, the energy sector can reduce its carbon footprint and lower operational costs. The research also highlights the importance of understanding the correlations between different mechanical properties of WGP-blended concrete, providing valuable insights for future developments in the field.
As the construction industry continues to seek sustainable solutions, the findings of this study offer a compelling case for the use of waste granite powder in concrete production. By embracing this innovative approach, the industry can move towards a more environmentally friendly and economically viable future. The research published in the Journal of Materials Science: Materials in Engineering, which translates to ‘Journal of Materials Science: Materials in Engineering’ in English, serves as a significant step forward in the quest for sustainable construction materials.
