Unconfined compressive strength of loose sandy soils ...
2019-8-1 · Unconfined compressive tests can determine the strength of cemented soils without the need to apply the confining stress, while maintaining the soil cementation or bonding prior to shearing. An increase in UCS of more than 345 kPa must be achieved for a treatment to be considered effective (ASTM D 4609, 2008).
