Zusammenfassung:The invention relates to a method for detecting water-soluble sulfate in gravel aggregate. The method is suitable for the field of hydropower engineering raw material detection. The technical problem to be solved by the invention is to provide the method for detecting the water-soluble sulfate in the gravel aggregate. According to the technical scheme adopted by the invention, the method for detecting the water-soluble sulfate in the gravel aggregate is characterized by comprising the following steps: preparing a powdery gravel aggregate sample, and pouring the sample into a container filled with distilled water, the weight of the sample poured into the container is m0, and the volume of the distilled water in the container is V0; taking an upper-layer clear solution from the container, and measuring the concentration c of SO4 < 2-> by using an ion chromatograph; and calculating the sulfate content Qs in the gravel aggregate based on the SO4 < 2-> concentration c, the sample weight m0 and the distilled water
