“…In the literature, there are many empirical equations developed for the indirect estimation of UCS with SH (Yılmaz and Sendir, 2002;Buyuksagis and Goktan, 2007;Çobanoǧlu and Çelik, 2008;Karaman et al, 2011;Bruno et al, 2013;Minaeian and Ahangari, 2013;Karaman et al, 2015;Tandon and Gupta, 2015;Jamshidi et al, 2016;Demirdag et al, 2018;Kong and Shang, 2018;Çelik and Çobanoğlu, 2019;Mesutoğlu and Özkan, 2019;Wang and Wan, 2019;Özkan and Kaya, 2020). However, since different types of hammers were used in these studies, very different empirical equations were derived.…”

Mechanical properties of rocks such as uniaxial compressive strength, tensile strength, shear strength are the properties that determine their behavior under load. These properties of rocks are often determined by difficult, complex, time-consuming and expensive test methods. Therefore, instead of determining these properties directly, these properties can be estimated indirectly by using relatively inexpensive, fast and easily applicable methods. The surface hardness parameter of Schmidt hammer rebound hardness is fast, inexpensive, and easy to apply to determine the hardness of rocks and concrete. It is also used to indirectly determine the mechanical properties of rocks. It is seen that two different types of hammers (N-type and L-type) with different impact energies are commonly used in the literature. In this study the correlations between the surface hardness of different rocks obtained using N-type and L-type Schmidt hammers were analyzed. For this purpose, data were compiled from studies in the literature, which included both N-type and L-type Schmidt hammer rebound hardness of different rock types, and the collected data were analyzed statistically. Coefficients have been proposed for the conversion of N-type and L-type Schmidt hammer rebound hardness to each other.
