In a groundbreaking study led by Rohit Raj from the Department of Civil Engineering at BIT Sindri, researchers are turning the tide on clayey soil challenges in engineering by harnessing the power of recycled materials. The study, published in ‘Discover Materials’, investigates the synergistic effects of crumbled rubber from discarded tires and tile powder on clayey soil performance, presenting a sustainable approach to soil stabilization that could revolutionize construction practices.
Clayey soils are notorious for their low shear strength, making them less suitable for a variety of engineering applications. Raj emphasizes the critical need for effective stabilization methods, stating, “Utilizing waste materials not only addresses environmental concerns but also enhances the performance of clayey soils, making them more viable for construction.”
The research highlights a series of laboratory tests where varying percentages of crumbled rubber were mixed with clayey soil, revealing that a 5% addition of crumbled rubber yielded optimal results. This mixture was then enhanced further with tile powder, where the introduction of 15% tile powder led to remarkable improvements in soil properties. The maximum dry density increased significantly, along with substantial gains in unconfined compressive strength and California bearing ratio values.
The implications for the construction sector are profound. By reducing reliance on traditional soil stabilization methods, which often involve costly and environmentally harmful chemicals, this innovative approach could lead to more eco-friendly construction practices. Raj notes, “The shift in failure behavior from brittle to ductile indicates that clayey soils can now better absorb stress, which is essential for structural integrity in construction.”
As the construction industry faces increasing pressure to adopt sustainable practices, the findings from this research could pave the way for optimized mixture designs that incorporate recycled materials. The potential for widespread application in geotechnical engineering is significant, suggesting a future where construction sites are not only more efficient but also contribute positively to environmental sustainability.
This research underscores a critical shift in how the industry can utilize waste materials effectively, transforming them into valuable resources. With further exploration, the combination of crumbled rubber and tile powder could become a standard practice, enhancing soil performance while also addressing the pressing issue of waste management.
