We are excited to announce that the latest research paper titled “Micro-Mechanical Behavior of Nanosilica-Treated High-Sulfate Soils” by Nripojyoti Biswas, Anand Puppala, Sayantan Chakraborty, and Dallas Little has been published in the Canadian Geotechnical Journal. The study explored the challenges posed by expansive sulfate-rich soils, which can lead to significant infrastructural damage due to the formation of ettringite when treated with calcium-based stabilizers. To address this, the authors investigated the benefits of integrating nano-silica admixtures with traditional Ca-based stabilizers. Through comprehensive engineering and microstructural studies, including advanced techniques like scanning electron microscopy and thermal analyses, they found that nano-silica effectively suppresses ettringite formation, promoting the creation of cementitious phases and enhancing the soil’s engineering performance.
The findings suggest that the application of siliceous nanomaterials can positively impact chemical treatments of sulfate-rich soils, leading to improved engineering outcomes.
