2.3. Strength and durability Although the uniaxial compressive strength test is a routine test and is performed frequently, there are only a few publications [21,22] relating this test to dura-bility. Eigenbrod [21] investigated the change in com-pressive strength with increasing moisture content. He concluded that compressive strength ...

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].
