| 摘 要： | 利用X射线衍射、TG-DSC综合热分析以及环境扫描电子显微分析技术等,研究了矿渣微细粉对水泥水化产物钙矾石、Ca(OH)2、CSH凝胶等的影响规律。研究结果表明,在水化早期,矿渣微细粉即参与水泥水化进程,显著影响水泥水化产物钙矾石、Ca(OH)2和CSH凝胶等的生成速度和生成量及微观形貌,并且随着其掺量增大及水化时间延长,矿渣微细粉参与水泥水化反应程度逐渐提高。

| Abstract: | The influences of slag ultrafine powder (SUP) on such cement hydration products as ettringite (AFt), Ca(OH)2 and CSH gel under different hydration time spans were studied by using XRD, TG-DSC and ESEM techniques. The results show that SUP participates in the cement hydration process and remarkably affects the formation rate, product content and morphology of hydration products. Moreover, with increasing SUP dosage and prolonging hydration time, SUP gradually further affects the cement hydration products. |
