Product Description
The Rock Schmidt Hammer is used for rock classification tests, offering a simple and user-friendly method akin to its application in concrete testing. Operating on the principle of rebound, it measures the impact energy generated by a 0.074 kg-m percussion on the surface of a rock specimen. The rebound index, indicative of the hardness or compressive strength of the rock, is determined by averaging several measurements taken perpendicular to the longitudinal axis of the specimen. This method allows for quick and non-destructive assessment of rock strength, particularly beneficial when obtaining core samples or conducting traditional laboratory tests is impractical or costly.
Standard
ASTM D5873 is a standard test method for determining rock hardness using the rebound hammer technique. It outlines procedures for assessing the surface hardness of rock materials, providing guidelines for test setup, calibration, and result interpretation.
