Abstract

A Schmidt hammer is a device designed to test the strength of concrete. More recently, the hammer has been used as a preliminary measure of rock strength. We took readings from the outcrop at Seth Green Drive, Rochester, NY and compared them to a more conventional measurement of strength, fracture density. The correlation of the best fit line relating the Schmidt hammer readings to fractures density was weak (R2=.076). As a result, we concluded that, at least for the strata examined there is no correlation between rock strength as measured by the Schmidt Hammer and fracture density.

176— Comparison of Using a Schmidt Hammer to Evaluate Strength of Rock to Conventional Methods
