Properties of Sodium Clay
- Low Permeability: Sodium clay, such as bentonite, has very low permeability due to its fine-grained structure and high plasticity. This property is crucial for preventing water from seeping through the core of earthen dams, ensuring stability and integrity.
- Low Porosity: While sodium clay does have low porosity, this is not the primary reason for its use in dam cores. Low porosity contributes to low permeability but is not the defining characteristic.
- High Strength: Sodium clay does not necessarily possess high strength; its strength is typically moderate and sufficient for the purpose of reducing permeability in the dam core.
- High Permeability: This property is undesirable for the core of earthen dams, as high permeability would allow water to seep through, potentially leading to erosion and failure of the dam.
