| 摘 要： | 为了探讨高温养护时钢渣复合胶凝材料的早期水化性能,采用了化学结合水的测定、浆体显微观察、X射线衍射分析和孔隙分析等手段进行了研究。结果表明:高温养护能明显缩短复合胶凝材料的水化诱导期,加快其早期反应速率;能够同时促进水泥和钢渣的水化,提高钢渣复合胶凝材料的水化程度。高温养护能改善复合胶凝材料浆体在水化早期形成的孔结构,降低孔隙率,减小粗孔比例;但对水化产物种类的影响很小。

| Abstract: | The early hydration characteristics of a complex binder containing steel slag under high temperature curing was studied by determining the non-evaporable water content,observing the micro appearance,X-ray diffraction and pore analysis. The results show that the dormant period of the complex binder is significently shortened and the early reaction rate is accelerated with high temperature curing.The hydration of both the cement and the steel slag is accelerated when they are cured at high temperatures and,th... |
