| 摘 要： | 烧结烟气脱硫灰中由于含有大量的亚硫酸钙和游离氧化钙,在将其直接用于胶凝材料时,不但延长凝结时间,降低早期强度,而且还容易导致水泥硬化体体积膨胀,恶化硬化体性能。实验研究了脱硫灰不同掺入方式和掺入量,以及氧化温度对复合粉反应性能的影响。结果表明,在将脱硫灰经过550℃氧化处理后,再采用加水预拌的方式,在脱硫灰掺入量为5%时可获得具有较好反应性能的复合粉。

| Abstract: | Sinter flue gas desulphurization ash contains lots of calcium sulfate and free calcium oxide,when it was directly used in curdle material,its coaqulation time is becoming length and early strength was reduced,it also easily leaded volume of cement scleroses expand and made scleroses＇s performance worse.In this study,affect factors of compound powder were discussed,such as the joined method,the joined level and the temperature of oxidation treatment.As the result showed,it can have a good reaction performance which used the method of processing of water with 5% desulphurization slag ash in compound powder after 550℃ oxide treatment. |
