Properties of Alkali Activated Slag Concrete
In order to study the effect of fiber and fly ash on the performance of alkali activated slag concrete, the effect of different fiber and fly ash content on the performance and mechanical properties of alkali activated slag concrete is analyzed and compared on the premise of optimizing the cement mixture ratio. The results show that fly ash increases the workability of ordinary concrete, while the addition of fly ash in alkali activated slag concrete reduces the workability of concrete. When the fiber content is 0.9kg/m3 and 1.8kg/m3, the compressive strength of alkali activated slag concrete at 28d is increased by 1.3% and 19.1%, respectively. The fly ash reduces the early compressive strength of the two kinds of concrete and increases the compressive strength after 28d.
