Abstract
As an indirect method, Schmidt hammer test has been employed to investigate correlation between uniaxial compressive strengths and blow values. To conduct the experiment, researchers have examined 11 types (1,417 blocks) of rock, which include igneous, metamorphic and sedimentary rocks in Korea. Every kind of rocks shows different blow behaviors in which correlations of rocks have been analyzed, thus leading to results in new formulas for strength predictions. Cross-check for reliability demonstrates high confidence. Newly proposed test method is highly valued for future research on Korean rocks.
