The aim of this study is to develop models for predicting mechanical properties of shales using available index parameters.

Mudrocks are common materials in civil engineering projects as construction materials for rock fills and embankments and in natural and undisturbed state in foundations, cut slopes, tunnel and underground spaces. These type of rocks...

The compressive strengtgh as a function of sample orientation was determined for two anisotropic fine-grained sedimentary rocks (siltstone and mudstone). The sample laminations were at orientation angles of 0, 15, 30,45,60,75 and 90 deg relative...

The effect of mineralogy on durability of 36 weak rock samples was investigated....

This paper sheds further light on the fundamental relationships between simple methods, rock

strength, and brittleness of igneous rocks. In particular, the relationship between mechanical (point load strength index Is(50) and brittleness...
