Point Load Index Tester
The point load index tester is used to perform the point load test. Generally consisting of components such as point load strength test machine, a loading frame with a100 mm scale attached to it, pressure gauge, quick release coupling and a bearing plate, this tester enables the economical testing of core or lump rock samples in either a field or laboratory setting. This testing method is also known as the point load test.
The point load test is an attractive alternative to the traditional and more common uni axial compressive strength test mainly because the point load test provides the same measurements but at significantly lesser costs. Due to this, the point load test is gradually replacing uni axial compressive strength test world over. These testers are robustly designed machines that are very long lasting and require minimal maintenance. Furthermore, these machines are very easy to operate and also have enhanced safety features for the operator. Affordable in prices, these are available in both standard and customized technical specifications.
Different Methods of Conducting Point Load Test Using Point Load Index Tester are :
Point load test can be conducted by four different methods using a point load index tester, these are,
Diametral Test – This test is generally conducted on large regular rock core samples.
Axial Test – This test is conducted when the rock core samples are of smaller size.
Block Test – Conducted on rock blocks.
Irregular Lump Test – Conducted when the rock samples are of irregular shapes.
Specifications for Samples That Can be Tested Using Point Load Index Tester :
The cores or lumps of rocks selected as samples should be representative of the true average of rock type under consideration.
The total number of cores or lumps shall be such, that at least 10 test specimens are possible per sample.
The test specimen should conform to the size and shape requirements for diametrical, axial or irregular slump testing.
Different core samples that are being comparatively tested should ideally be from the same bore hole, same geological horizon and within the shortest possible difference in their respective elevations in the bore hole.
Unless tests on dry rocks are specifically required, the rock sample that is going to be tested should ideally have a water saturation level of over 50 percent.
