The Granites that occur at Nang San, Baik Gu and Hwang Doung used for test in this report. In this test, 30 rock blocks, 1X1X1cm(1㎤), were prepared and the stress-strain diagrams were measured by PS. 7/LT type strain meter under uniaxial Compressive load state. In the tests obtained results are as follows ; (1) The stress strain diagrams of Nang San, Hang Doung and Baik Gu granites are increasing at low stress, decreasing at high stress and increasing greatly before failure (2) The strain for Nang San and Hwang Doung granites tested under Uniaxial Compression to failure are similar each other, but that for Baik Gu granite is increasing greatly more that these.
