| 摘要: |
| 主要研究了不同铝铁比的铁相固溶体对硅酸三钙（C3S）水化性能的影响.结果表明，铁相固溶体对C3S的水化具有抑制作用，并且其铝铁比越低，该抑制作用越明显.借助等温量热仪、电感耦合等离子体发射光谱仪（ICP-OES）等测试手段发现，铁相固溶体水化后产生偏铁酸根离子和偏铝酸根离子，其中偏铁酸根离子会阻碍氢氧化钙的沉淀，从而抑制C3S的水化，而偏铝酸根离子可以减轻偏铁酸根离子对C3S水化的抑制作用. |

| 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. |
