dc.description.abstractThe self-sealing/self-healing (SS/SH) liner system
is based on the fundamental principle that an impermeable
seal is self-formed and self-healed by the pozzolanic reaction
at the interface between two adjacent reactive layers.
The objectives of this study were to evaluate the effect of
contaminants on the performance of an SS/SH liner used
as a hydraulic barrier, to understand mechanism of volatile
organic compound (VOC) sorption on the SS/SH materials,
and to estimate the mass transport parameters of contaminants
through the SS/SH liner materials.The hydraulic conductivity
of the liner material decreased continuously with
time, and stabilized at less than 1 10 7 cm/s after approximately
15 days. It is known that the seal at the interface
between two reactive layers is self-formed over time, and
this contributes to the decrease in the hydraulic conductivity
of such a liner system.The retardation of the seven target
VOCs tested was greater in the SS/SH liner materials than
in a clayey soil specimen owing to the higher sorption
capacity. An analytical solution developed to test column
equipment could reduce the time required to estimate
the hydrodynamic dispersion coefficients of organic compounds
by using the data on changes in concentration in the
upper reservoir of the column.
