Abstract
In this study, the erosion behavior of ions in lining concrete incorporating fly ash and silica fume under the combined action of load and flowing groundwater containing composite salt. The results show that the transmission speed of Cl− and SO42− in lining concrete under different erosion conditions is: flowing groundwater–load action in the tension zone > flowing groundwater > static corrosion solution > flowing groundwater–load action in the compression zone. The addition of silica fume (SF) and fly ash (FA) can reduce the concentration of Cl− and SO42− in lining concrete, increase the ratio of combined Cl− to total Cl−, and reduce the ratio of combined SO42− to total SO42−. The addition of FA and SF can increase the lining concrete's resistance to Cl− corrosion by about 10–28%, and SO42− radical resistance by about 5–12%, and the more FA is added, the greater the increase.
