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.
