- •
Ball-bearing effect of fly ash allows higher fine aggregate content in SCC.
- •
Ball-bearing effect of air bubbles further enhance self-compactability of concrete.
- •
Various types of air-entraining agent leads to different stability of air bubbles.
- •
Fly ash causes higher amount of instable large entrained bubbles.
- •
Spherical shape of fly ash also leads to instability of entrained air bubbles.
