๐ Thrilled to share the latest publication in the esteemed ASTM’s Geotechnical Testing Journal: “Experimental Studies and Sustainability Assessments of Quarry Dust for Chemical Treatment of Expansive Soils” by our very own Dr.ย Nripojyoti Biswas, Dr.ย Anand Puppala, and Dr.ย Sayantan Chakraborty, Ph.D.
๐ก The research is focused on addressing the issues of damage and serviceability loss caused by moisture-induced volumetric changes in constructions on expansive soils. The research dives deep into a more sustainable soil stabilization method โ replacing the traditionally used calcium-based stabilizers that increase the carbon footprint and greenhouse gas emissions with silica-rich waste products, such as quarry dust. ๐ฌThe study involved extensive engineering tests, including unconfined compressive strength tests before and after moisture conditioning, one-dimensional free swell tests, and linear shrinkage tests. Quarry dust significantly enhances the performance of problematic soils, reducing the shrink-swell potential to a greater extent than the traditional lime treatment.๐ Perhaps the most notable finding from the research is the potential for quarry dust to be a sustainable alternative. This means we can reduce the geo-environmental issues related to handling and stockpiling waste products in landfills.๐ฑ The authors believe the findings represent an exciting leap forward for the construction industry. By repurposing waste products, we can not only improve the quality of our structures but also make a positive impact on the environment.
Excited to see where these findings lead us next!
