WebPoint Load Index (Strength) ASTM D 5731 Purpose To determine strength classification of rock materials through an index test. Procedure Rock specimens in the form of core (dia metral and axial), cut blocks or irregular lumps are broken by application of concentrated lo ad through a pair of spherically truncated, conical platens. WebPoint 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...
WebDuring the process of mechanized excavation, rock is essentially subjected to cyclic point loading (CPL). To understand the CPL fatigue behavior of rock materials, a series of CPL tests are conducted on sandstone samples by using a self-developed vibration point-load apparatus.
