THE EFFECT OF SAMPLE SIZE ON THE FLEXURAL STRENGTH OF SEDİMENTARY CARBONATE ROCKS UNDER CONCENTRATED LOAD

Flexural strength is an important mechanical property used in the selection of application area natural building stones. The flexural stones our country determined according to test standards prepared by European Union. According TS EN 12372, recommended sample dimensions for determination are 50×50×300 mm. However, generally, 20-30 mm thick plates flooring, cladding, and exterior applications buildings. In practice, 50 rarely used, as well preparing samples a laborious time-consuming process. this study, it has been investigated how much size affects sedimentary carbonate rocks when using two different sizes. It observed that values obtained from sizes same rock very close each other. Besides, stress distributions formed on were analyzed with ANSYS Workbench 2020 R1. sizes, exposed load, occur regions, concentrate.
