摘要: 通过测定活性二氧化硅、氧化铝含量及红外光谱分析等方法研究粉煤灰、煤粉炉渣等硅铝质工业废弃物的蒸压反应活性。结果表明,硅铝质工业废弃物的蒸压反应活性与其活性二氧化硅、氧化铝含量及红外光谱1 100 cm-1附近强吸收区的Si—O伸缩振动频率存在明显的对应关系,即活性二氧化硅、氧化铝含量越高,红外光谱1 100 cm-1附近强吸收区的Si—O伸缩振动频率越低,蒸压反应活性越强,蒸压制品强度越高。

Abstract: Mass fractions of active SiO2 and Al2O3,and infrared spectrum (IR) were used to analyze the autoclaved reaction activities of Si/Al-based industrial residues,such as fly ash and coal dust slag etc.Results showed that autoclaved reaction activities of Si/Al-based industrial residues had an evident relationship with the mass fractions of active SiO2 and Al2O3,and Si-O stretching vibration frequency about 1 100 cm-1 in strong absorption region of IR,that is the more mass fractions of active SiO2 and Al2O3,and the lower Si—O stretching vibration frequency about 1 100 cm-1 in strong absorption region of IR,the stronger autoclaved reaction activities and the higher compressive strength of autoclaved products. 
