Point Load Test | How to Break Rock in One Minute | Experimental procedure

Point load test is commonly used to estimate the strength of rock or concrete. It is a simple test that can be used for almost all types of rock samples. In this video, sandstone core samples were tested. This video also shows what can go wrong with this test and how we shall be mindful of of the obtained results.
0:00 Sample measurements
02:45 Test 1, long core sample
05:30 Test 2, axial load on weathered samples. Be careful with the obtained results.

I hope this video is useful to you; if so, please share and like. The data analysis will be discussed in the next video, which is currently being recorded. You can also find it in my book called 'Rock mechanics through project-based learning'.
