... stood against performing point load index tests on soft rocks the results look comprehensible. Formerly performed tests on similar rock types in the same region could be confirmed. The compressive strength for load conditions perpendicular to the foliation/stratification (load angle α = 0°) decreased...

Paper presented at the ISRM International Symposium - EUROCK 2012, May 28–30, 2012
Paper Number: ISRM-EUROCK-2012-111
... Abstract: It is common engineering practice to estimate the Unconfined Compressive Strength (UCS) of a rock, by multiplying Point Load Index test (IS50) results by a cor-relation factor. The IS50 to UCS correlation is reasonably accurate for crystalline or isotropic rocks but with weak...

... the highest and lowest values from all tests, as recommended by the ISRM suggested methods, a total of 11 samples was obtained and the average value for the point load index Is(50)was 7.88 MPa, with values ranging from 6.01 to 9.7 MPa. The coefficient of variation was 14.62%, for an average index Is of 7.47...
