| Abstract: | Surface hardness tests such as Shore hardness (SH) and Schmidt hammer rebound hardness (SR) may provide a quick and inexpensive
measure of rock hardness, which may be widely used for estimating the mechanical properties of rock material such as strength,
sawability, drillability and cuttability. In the marble industry, circular sawing with diamond sawblades constitutes a major
cost in the processing. Therefore, several models based on the relations between hourly slab production (P
hs), rock surface hardness (SH and SR) and mineral grain size (S
cr) were developed using the data obtained from field and laboratory measurements on five different marbles quarried in the
Mugla Province of Turkey. The models which include surface hardness and crystal size may as well be used for the prediction
of sawability (hourly slab production) of carbonate rocks using large-diameter circular saws. |
