Hardness Testing of Polymer Concrete Castings by Schmidt Hammer
Materials Today: Proceedings, 2020Abstract Presented paper is focused on testing the hardness of polymer concrete castings by Schmidt hammer. The first part of the paper describes the theoretical knowledge from the material area of the issue. The experimental part of the paper is devoted to the production process of the polymer concrete castings and to the materials, machines and ...

Evaluation of Schmidt Hammer Rebound Hardness Test Holders
Geotechnical Testing Journal, 1984Abstract An evaluation is made of three different holders for Schmidt hammer tests on rock core in the laboratory, including steel angle, V-notch, and semicircular groove holders. The differences are small, but it is shown that the V-notch holder gives consistently higher rebound hardness values.

Evaluation of Laboratory Schmidt Hammer Tests on Carbonate Rocks
Proceedings, 2013Being quick, inexpensive, non-destructive and handy, the Schmidt Hammer (SH) test has been widely used to determine hardness and to predict the unconfined compressive strength (UCS) of rocks. However, a review of empirical equations recommended for determination of the USC of rocks based on the SH rebound number (N) suggests that one unique formula ...
