Objectives of the study
Cement stabilized soil (cemented soil) technology is an important technical means to improve the poor soil properties such as mucky clay The existing research on the development mechanism of cemented soil performance is mostly focused on the hydration of cement to characterize the products and microstructures However, there is still a lack of analysis of the nanoscale interface bonding mechanism between hydration products and clay minerals in cemented soil and the interface energy source of cemented soil Molecular Dynamics MD) method can effectively explain the interactions and energy variations between different phases from the nanoscale However, due to the need to consider the role of clay minerals, model construction and verification are more complicated The current research focuses on the mechanical and structural evolution of a single material under different variables There is little analysis of the dynamic mechanism of the interaction between cement hydration products and soil mineral interface areas in cemented soil, and the mechanism of performance improvement of cemented soil has not been fully elucidated
