2.Usage

The rock point load tester is a test instrument for rock point load test and determination of rock point load intensity index. According to the rock load intensity index, the uniaxial compressive strength of the rock can be calculated and the anisotropy of the rock (ie, the ratio of the maximum and the minimum in the load intensity of the different points) can be determined. The weathering zone is determined, Rock grading and so on.

Rock point load tester is a suitable for the construction site using the test equipment. The point load test requires a lower preparation of the rock sample, which may be a rock specimen for engineering exploration or a slightly trimmed irregular specimen. Specimen preparation without specialized mechanical processing, compared with the conventional test, with a fast test, the test cycle is short, the method is simple, low cost characteristics. Can be widely used in geology, mining, hydropower, railways and transportation and other construction projects in the field test. The Rock Point Load Test was first published in 1972 by the International Society of Rock Mechanics Test Methodology Committee as one of the methods for determining rock strength. The International Society of Rock Mechanics Test Methodology Committee revised the method in 1985. The rock load intensity has been widely used in China's national standards and many departmental norms.
