| Abstract: | A kind of high strength silica fume concrete C70, which is of good cavitation resistance and abrasion resistance, is used in the Xiaolangdi flood discharge project. In combination with practice, a discussion is made on the causes and prevention of cracking in high strength (70MPa) mass concrete during early and later period of construction. Two methods for crack treatment are introduced, i.e. epoxy resin injection and extra fineness cement grouting. |

| Keywords: | high strength concrete crack epoxy resin extra fineness cement |
