Rock point load test
The point load test is an index test used to categorise rocks based on their strength. The test can be used to calculate uniaxial compressive and tensile strengths, as well as other properties of entire rocks with which it correlates. Both the anisotropy index (Ia (50)) and the strength index values at a given position are determined by the test. The strength ratio under point load in the directions with the lowest and highest values of the strength index is represented by the anisotropy index. The sample load and force gauges are part of the test apparatus, and the sample dimensions (length scale) are also measured while the sample is being tested. Point load testing can be divided into three categories: axial, diametral, and block or lump. On rock core samples, the axial and diametral tests are performed. Diametral test: A rock core sample is used for the diametral test. In order to determine the average value of the point load strength index, a minimum of 10 test specimen...
