01.06.2000  International Journal of Rock Mechanics and Mining Sciences. The Schmidt Hammer was developed in 1948 for non-destructive testing of concrete hardness [1], and was later used to estimate rock strength [2,3]. It consists of a spring-loaded mass that is released against a plunger when the hammer is pressed onto a hard surface.

Schmidt hammer - Wikipedia

A Schmidt hammer, also known as a Swiss hammer or a rebound hammer or concrete hammer test, is a device to measure the elastic properties or strength of concrete or rock, mainly surface hardness and penetration resistance. It was invented by Ernst Schmidt, a Swiss engineer. Testing the compressive strength of a concrete cube using Schmidt hammer.

The point load test for weak rock in dredging applications ...

The point load test is shown useful for weak/saturated rocks which are commonly encountered in mechanical dredging operation. To support the dredging use of the point load test, orginally intended to obtain a field strenth index for hard rock materials, a comparative, testing program was initiated, which included more than four hundred rock tests.
