| 摘要: |
| 钛石膏是一种化工废石膏，研究了热处理对钛石膏－粉煤灰复合胶凝材料物理性能的改性作用，研究结果表明，采用低温煅烧可激发钛石膏的化学活性，大幅度缩短钛石膏－粉煤灰胶凝材料的凝结时间，提高强度，因此，该方法不失为一种行之有效的改善钛石膏－粉煤灰复合胶材料性能的措施。 |

| Abstract: |
| The modification of composite using waste chemical gypsum from TiO 2 production and fly ash was studied. The results show that calcination of the gypsum in lower temperature can excite the hydration activity of this gypsum, shorten the setting time and increase the strength of composite modified by waste chemical gypsum and fly ash. In fact, it is an effective way to improve the properties of this composite. |
