Laboratory rock index / Alexcius Daut

Laboratory rock index is a mean of classifying the rock with its properties. To determine the index property of the rock, series of testing conducted on rock samples must comply with the suggested method of testing outlined by the International Society of Rock Mechanic (ISRM). By knowing and understanding the properties of the rock engineer can determine the potential usage of rock as construction materials and the role of rocks in the civil engineering related work as well as the engineering application of rock. Rock engineering is now gaining popularity in Malaysia and a lot of construction involving rock engineering such as tunneling, underground opening, rock excavation, mining and quarrying had been introduced or improved for the last three decades. Thus, knowledge in this part of engineering branch is vital for the future engineers.
