| 摘 要： | 通过试验研究了掺加超塑化剂前后水泥净浆流动度的变化,并结合光学显微镜观察相应的水泥絮凝结构,讨论了微观絮凝结构与宏观流动度的联系.得出结论,水泥的絮凝结构中确实包裹了大量的自由水,严重影响了水泥的流动性.同时还应用分形理论得出水泥絮团属于典型的分形结构,其分形维数为1.846 8.

| Abstract: | Fluidity of cement paste as well as mixing with water reducing agent were studied,at the same time,cement flocculated structure were observed by using microscope.Discussed the relationship of flocculation and fluidity.A conclusion can be drawn that a large number of water are enclosed by flocculated structure,which influence cement fluidity greatly.Furthermore studied the flocculated structure with fractal theory,the result show that the flocculation are typical fractal structure and the fractal dimension is 1.846 8. |
