Request PDF on ResearchGate | Mechanical Properties of Clays and Clay Minerals | Consistency and strength of cohesive and non-cohesive soils are very different. In general, higher clay contents in a soil cause higher plasticity, greater shrinkage and swell potential, higher compressibility and lower shear strength.
Because of these properties, clay is used for making pottery, both utilitarian and decorative, and construction products, ... Clays and Clay Minerals, 43 (2): ...
9.1. Clays in Civil Engineering. In civil engineering, the relationship between the visual–mechanical behaviour of clays and the properties of clay minerals at the nano- and meso-scales (usually referred to as 'micro-scale') is well recognized.
Six types of clays are mined in the United States: ball clay, bentonite, common clay, fire clay, fuller's earth, and kaolin. Mineral composition, plasticity, color, absorption qualities, firing characteristics, and clarification properties are a few of the characteristics used to distinguish between the different clay types.
