Description
Summary:ABSTRACT This study introduces N-MBER, a novel soil stabilizer incorporating nano-SiO2, which significantly enhances the strength of cement-based soil mixtures. Experimental results show that N-MBER exhibits an exponential increase in strength over time, with strength improvements ranging from 15% to 50% compared to conventional stabilizers, depending on the nano-SiO2 content. The primary mechanism driving this enhancement is the increased formation of calcium silicate hydrate (C-S-H) gel, which contributes to improved durability and load-bearing capacity. Additionally, the nano-SiO2 improves particle structure, leading to greater overall stability. These advancements suggest that N-MBER not only improves soil stabilization but also has potential for reducing waste by minimizing reliance on traditional cement-based stabilizers. This development offers valuable insights into soil treatment techniques and presents a sustainable solution for infrastructure projects where soil strength is critical.
