Expansive clays, upon wetting, exhibit unique characteristics such as low permeability, high swelling pressure, and self-healing properties, making them used in modern engineering projects, especially as engineered geological barriers for nuclear and municipal waste disposal. However, their effectiveness depends upon many environmental factors.

The research focuses on a deeper understanding of optimized design and performance by developing a comprehensive chemo-hydro-mechanical constitutive model to enhance our understanding of how environmental factors such as chemical interactions, hydraulic conditions, and mechanical loading affect the behavior of compacted expansive clays over different time scales. The research aims to bring new insights for the prediction of the performance and longevity of geological barriers.
