There are three main types of geosynthetic clay liners (GCLs) available: sodium bentonite GCLs, calcium bentonite GCLs, and mixtures of both. Sodium bentonite GCLs have a higher swelling capacity and are more commonly used in landfill and containment applications. Calcium bentonite GCLs have lower swelling capacity but are preferred in applications where high permeability is required. Mixed GCLs combine the characteristics of both sodium and calcium bentonite to provide a balance between swelling capacity and permeability.
There are several types of geosynthetic clay liners (GCLs) available, including sodium bentonite-based GCLs, calcium bentonite-based GCLs, and hybrid GCLs that combine both types of bentonite. Each type has its own unique characteristics and performance attributes, allowing for a range of options to suit specific project requirements. Sodium bentonite-based GCLs are commonly used for their high swelling capacity and low permeability, while calcium bentonite-based GCLs offer enhanced shear strength and chemical resistance. Hybrid GCLs provide a balance between the two, offering a combination of swelling capacity, permeability control, and stability.
There are several types of geosynthetic clay liners (GCLs) available, including sodium bentonite GCLs, calcium bentonite GCLs, and polymer-modified GCLs. Sodium bentonite GCLs are commonly used due to their high swelling capacity and excellent hydraulic conductivity. Calcium bentonite GCLs offer similar properties but with a lower swelling capacity. Polymer-modified GCLs are enhanced with polymers to improve their strength and durability.
