Abstract：The impact of iron phase solid solutions with different aluminum-to-iron ratios on the hydration performance of tricalcium silicate(C3S)was investigated.The results show that iron phase solid solutions inhibit the hydration of C3S,and the lower the aluminum-to-iron ratio in the iron phase solid solution,the more significant the inhibition on C3S hydration.Using testing methods such as isothermal calorimetry and inductively coupled plasma optical emission spectrometer(ICP-OES),it is found that iron phase solid solutions produce metaferrate and metaluminate ions after hydration.The metaferrate ions hinder the precipitation of calcium hydroxide,thereby inhibiting the hydration of C3S,while the metaluminate ions can mitigate the inhibitory effect of the metaferrate ions on C3S hydration.
