Abstract

The possibility of increasing the usage of Fly ash (FA) in concrete has been a subject of interest and investigation by the authors. In the previous work, a composite of Fly ash- β- cyclodextrin (FA-β-CD) has been seen to have the tendencies of improving hydration reaction. To have further insight on how this composite can affect the mechanical properties of concrete, its rheological properties (viscosity and setting time) are assessed in this article. FA was used in percentages of 30 and 50, while β-CD was used in 0.025, 0.05 and 0.1 percentages. These percentages were based on the total percentage of cement (by mass). The results showed that increased in FA and β-CD contents, reduced the viscosity of the cement paste. Also, higher contents of FA and β-CD, reduced the water required for consistency and extended the setting times.
