CLASSIFICATION OF ROCKS ON THEIR CREEP BEHAVIOUR AT LOW STRESS LEVELS

Abstract

In this study, it is aimed to classify rocks on their time-dependent properties. Bending creep tests on cantilever beam specimens are carried out at low stress levels. Four different rock types, namely Marble (Afyon), Marl (Tuncbilek - Kutahya), Sandstone (Beytepe - Ankara) and Tuff (Incehisar - Afyon) are used in these creep tests. Each rock type was tested four times at five stress levels, namely, at 10%,20%,30%,40%, and 50% of their average instantaneous bending strengths. The test results are analyzed with the percent deformation criterion using ternary diagrams.
