STUDENT Appendix A: Laboratory Testing Procedures Reference: AS 4133.4.1 - 2007 Reconfirmed 2016 Method of testing rocks for engineering purposes - Method 4.1: Rock strength tests - Determination of point load strength index PROCEDURES: General: Obtain and set up the point load testing machine according the RMIT University Policy. Perform the necessary calibration of the equipment as suggested by your teacher. Select rock samples containing sufficient material for the required number of test specimens from each domain of the rock mass for which point load strengths are required. Samples in the form of core are preferred for more accurate strength classification. Specimens shall be tested at close to their in situ moisture content. Loading rates shall be applied without shock such that failure is obtained 30 s to 3 min after commencement of loading. Diametral Test: The procedure shall be as follows: Select core specimens with a length/diameter ratio greater than 1.0. Insert each specimen in the loading device and close to the platens to make contact along the core diameter, ensuring that the distance ( L ) from the contact points to the nearest free end is at least 0.5 D , where D is a distance between the contact points (see Figure 1). Increase the load to failure then record the distance ( D ). Record the failure load ( P ) and failure mode for each specimen. Axial Test: The procedure shall be as follows: Select core specimens with a length/diameter ratio of 0.6 to 1.0 (see Figure 1). [LabReport1_VU22484_AT1_Student_28042020] [1 of 4 ] [28/04/2020] Student product assessment task © Content is subject to copyright, RMIT University FINAL APPROVED – STUDENT PRODUCT ASSESSMENT TASK TEMPLATE – June 2019_Version 2.0 Page 5 of 22

STUDENT Insert each specimen in the loading device and close to the platens to make contact along the core axis. Increase the load to failure then record the distance ( D ). Record the failure load ( P ) and failure mode for each specimen. Figure 1: Shape Proportions and Equivalent Core Diameter of Test Specimens (AS 4133.4.1) CALCULATIONS: The following shall be calculated. The point load strength and point load strength index. (i) For Diametral Tests: (A) The uncorrected point load strength ( I S ) from the following equation: I S = P × 1000 D 2 where I S = uncorrected point load strength (MPa) P = load at failure (kN) D = platen separation (mm) [LabReport1_VU22484_AT1_Student_28042020] [1 of 4 ] [28/04/2020] Student product assessment task © Content is subject to copyright, RMIT University FINAL APPROVED – STUDENT PRODUCT ASSESSMENT TASK TEMPLATE – June 2019_Version 2.0 Page 6 of 22
