Abstract: Ten different rocks obtained as drill cores from various localities in Malaysia were tested in the laboratory for their index and engineering properties. The rock properties investigated include the dry density, the Shore scleroscope hardness, the point load strength index and the unconfined compressive strength. An attempt is then made to correlate these properties so as to enable one to predict the unconfined compressive strengths of rocks based on the results of the more easily carried out index tests (such as the Shore hardness and/or point load tests).
The various test methods are also discussed briefly, including the effect of the variation of sample length/diameter ratio in the point load test.
