Modification and Stabilization of Collapsible Loess Using Diammonium Phosphate Solution
CrystalsThe collapsible loess will rapidly soften and lose its bearing capacity when soaked in water. Under a mild condition (20 °C), the biomimetic inorganic agent, diammonium phosphate (DAP), reacts with calcite in the collapsible loess, producing a stronger ...
