Cohesive soil is a type of soil that has particles that stick together due to their fine texture and moisture content. This soil typically includes clay and silt, which have small particle sizes that allow them to bond effectively. The cohesive nature of this soil makes it suitable for construction and agricultural purposes, as it can retain water and nutrients. The strength and stability of cohesive soil are influenced by its moisture content. When wet, cohesive soil can become soft and pliable, while drying can lead to cracking and hardening. Understanding the properties of cohesive soil is essential for engineers and builders when designing foundations and other structures.
