This study focuses on the difference in physical, mechanical and degradation properties for red shale and black shale exposed in Daegu area, Korea. The different color of shale indicates a variation of sedimentary environments during the Cretaceous era in Jurassic period, and thus the engineering properties of the shale are also expected to be varied. The red shale samples are obtained from the Haman Formation while the black one is from the Banyawol Formation of the Hayang Group in the Gyeongsang Supergroup. A series of laboratory tests including physical property test, ultrasonic velocity test, uniaxial compressive test, point load test and slake durability test were conducted on about 500 specimens of shale. The properties obtained from the tests are correlated each other and some empirical equations are deduced. The chemical and mineral composition investigated by using XRF, XRD and SEM are very similar each other.
According to the test results, unit weight of both shale is very similar but absorption ratio and porosity of the red shale are a little higher than the black one. Mechanical properties such as ultrasonic velocity, uniaxial compressive strength and point load strength of the red shale are higher than the black one. However, the point load strength and the slake durability of red shale is more easily decreased comparing to the black one by increasing of the submerged period in pH 3.0 and 5.6 solution.
