I. Understanding GCLs: Specifications and Standards
What Are GCLs?
Geosynthetic Clay Liners (GCLs) are thin prefabricated clay liners consisting of sodium bentonite (Na-B) sandwiched between two geotextiles. These materials have gained significant popularity due to their low permeability, strong resistance to dry-wet and freeze-thaw cycles, self-healing capabilities, and adaptability to uneven settlements. Introduced into the American market in the late 1980s and later introduced to China in the late 1990s, GCLs have become one of the most promising new seepage-proofing materials globally. Their applications span various industries, including environmental engineering, mining waste management, and coal combustion product disposal.
Specifications
Specification | Typical Value |
Thickness | 5-10 mm |
Bentonite Content | 4000-6000 g/m² |
Permeability | <1 x 10^-9 cm/s |
Tensile Strength | >15 kN/m |
Peel Strength | 360 N/m |
Performance Standards
GCLs are tested and certified under various international standards to ensure reliability and safety. These include:
l ASTM D5887 for hydraulic conductivity.
l ASTM D6496 for internal shear strength.
l ISO 10318 for general terminology and application guidelines.
Applications
l Landfill Liners: Prevent leakage of hazardous substances.
l Mining Operations: Contain contaminated water and chemicals.
l Wastewater Treatment: Provide long-lasting barriers for liquid containment.
