Abstract

The Qingxi Formation black shales which are distributed in Sanjiang region of Guangxi province, China, are studied as the object in this paper. The mineralogical and chemical compositions of rock and weathering product samples were determined by X-ray diffraction and X-ray fluorescence spectrometer. According to the chemical reactions involved in the black shale oxidation process, the corrosion impact of acidic aqueous solution produced by the black shale chemical weathering on the concrete components were analyzed. Furthermore, the sulfate minerals as the significant weathering products are characterized by volume expansion in the cyclic wet-dry environment. It is indicated that black shale oxidation process can bring acid corrosion to the surrounding rocks and construction materials.
