| Abstract: | By testing the plastic index, firing performance, radioactivity and compressive and shear strength of shale in beijing west mountain JieShi-Hexi area, this article analyzes the deposit genesis, the shale ore-controlling geological conditions, ore mineral components, ore type and the mineral chemical composition. The results show that the shale has large reserve, stable chemical properties, appropriate plasticity index, good forming performance, wide firing range, low radioactivity, good compressive and shear strength and so on, so that it is suitable for making fired wall materials. |
