Engineering properties of mudstone
WebFine-grained, clay-rich soils can absorb large quantities of water after rainfall, becoming sticky and heavy. Conversely, they can also become very hard when dry, resulting in shrinking and cracking of the ground. This hardening and softening is known as ‘shrink–swell’ behaviour. WebIn engineering works, the mudstone can be encountered in a range of weathered states. When carrying out tests to derive relevant engineering properties, it is important to …
