The detached clay particles directly filtrated through the sand-clay mixture lead to suffusion; however, if the detached clay particles are subjected to reattachment, the degree of suffusion may be less significant. This study investigates the impact

Applied Sciences, Vol 9, Iss 5, p 932 (2019)
The presence of retained colloidal particles causes the retardation of contaminant transport when the contaminant is favorably adsorbed to colloidal particles. Although the particle size distribution affects the retention behavior of colloidal partic

Suffusion is a type of internal erosion caused by the detachment of fine particles. Additionally, continuous suffusion reduces the stability of geotechnical infrastructures. In this study, the impact of clay mineralogy and sand grain size on the suff

Clay particle deposition in porous media is critical in many geotechnical applications that rely on filtration. The deposition of particles in the filter medium can result in clogging, which causes a reduction in the hydraulic conductivity of the fil

The treatment of coal ash produced at coal-fired power plants requires high costs and has environmental problems. Therefore, a high proportion of coal ash has been reused, and the effective reuse of coal ash has been investigated extensively. In this

Internal erosion by suffusion within a sand–clay mixture may occur as detachment of clay particles, which is induced by a decrease in ionic concentration (IC) along with application of a high hydraulic gradient. Through designed laboratory soil-col

In this study, we performed one dimensional cylindrical sedimentation tests to investigate the impact of clay mineralogy, ionic concentration, ionic valence on sedimentation, and self-consolidation behavior of clay. The result at 1,000% and 2,000% wa
