Abstract

In general, 37 degrees is applied to the internal friction angle value ( ¢) of concrete and an 8 ....... 10% value of compressive strength is for the tensile strength value of it. However, the theoretical solution of the internal friction angle is calculated as 57.5 degrees by the equivalence that linear elastic theoretical solution of the concrete split test is equivalent to the wedge theoretical solution of it. We experimented with the partial compression test of plain concrete to ensure this fact. As a result, it was proved that the test result equal to the wedge theoretical solutions at ¢ =55 degrees and Ft=O.OSFc.
