6.Why geosynthetic clay liner can be waterproofing?
Bentonite has good adhesion, swelling, colloidal dispersion,
thixotropy and cation exchange properties. When bentonite is
hydrated, water molecules are adsorbed along the surface of the
Si-Al-Si structural unit, which increases the distance between
adjacent structural units. After hydration, the surface cations of
bentonite are in a hydrated state, and after absorbing H2O, it
becomes saturated and becomes a gel, and its durability can reach
200 years. In the confined space, the continuous water absorption
and expansion make the waterproof blanket layer itself dense and
its volume increases, so that it has a waterproof function by
forming a negative pressure inside. Its permeability can be reduced
to 10~9cm/s, and it is almost watertight.
