The unconfined compressive strength (UCS) of stabilized soil with lime and cement is a crucial mechanical factor in developing accurate geomechanical models. In the past, determining UCS required laborious laboratory testing of core samples or complex well-log analysis, both of which consumed many resources. This study introduces a novel method for …

In term of UCS, sandstone and dolomite tend to have higher mechanical strength and density compared to limestone and marl limestone. Sandstone varies widely in strength depending on its cementation and grain size. Marl limestone, due to its higher clay content, is generally softer and less durable than the other three lithologies [32].
