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.

Watch the second part to learn how to analyse the data obtained in this video:

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'.

very good example of samples results that we need to discard

thank you😭 tomorrow i have a test on this and your video helped me understand better.

you great sir, no better teacher be there but you

[antonybubbler]

Man youve killed it it man😂😂💯love the good work you are doing though.

Thanks! I suppose for axial test, sample should be properly prepared for evenly distributed forces. In rock lab all samples cut with microns precision.

in 0:57, why measure the length of the sample(L) from the middle???

[addisubekele]

what is the difference between this point load tests and model PIL-7 point load tests on rock strength tests??

You didn’t mark it at all. You skipped an entire step
