The Schmidt Hammer in geomorphological research

Progress in Physical Geography, 2006
The Schmidt Hammer, originally designed for testing the hardness of concrete in 1948, was first used in a geomorphological context in the 1960s. Since then the advantages and disadvantages of the device for measuring rock characteristics have become apparent, and the Schmidt Hammer has been used for an increasing range of purposes, including the study ...

The Schmidt hammer in rock material characterization

Engineering Geology, 2005
The Schmidt hammer provides a quick and inexpensive measure of surface hardness that is widely used for estimating the mechanical properties of rock material. However, a number of issues such as hammer type, normalization of rebound values, specimen dimensions, surface smoothness, weathering and moisture content, and testing, data reduction and ...

The schmidt hammer, weathering and rock surface roughness

Earth Surface Processes and Landforms, 1991
AbstractMeasures of the differential relief of adjacent feldspar and pyroxene grains provide the first clear negative correlation of Schmidt hammer rebound (R‐) values and degree of weathering. However, weathering and roughness are intimately related, so the latter cannot be seen simply as a source of error limiting the utility of the Schmidt hammer ...

Hardness Testing of Polymer Concrete Castings by Schmidt Hammer

Materials Today: Proceedings, 2020
Abstract 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 ...
