In this paper, we examine the crack extension behavior in the brittle material under the compression mixed mode loadings. We here employ cement pastes as the brittle materials. Two initial parallel cracks were inserted in the center of the disc-type test-piece. The compressive loads were obliquely applied to the initial cracks. The experimental results were examined using the energy release rate criterion. The energy release rate is computed for all the extending crack tips at the onset of crack kinking by using the E-integral which is path independent even for a path containing a kinking crack tip and stationary crack tips.
