Fly ash: - Fly ash availability was not an issue with us. But fly ash Blaine was around 280-290 m2/Kg, which we require up to 320 m2/Kg. But Blaine of Fly ash was not in our control and Flyash cannot be ground solely to achieve required blain size. So it was a cause with no solution. Gypsum: - Size of gypsum boulders were very high than required.
