The loss on ignition (LOI) content of ground bagasse ash is
rather high at 8.16%, which close to the limit of 10% specified by
the ASTM C 618 standard for class N pozzolan [12]. Other pozzolanic
materials, such as rice husk ash have LOIs that can be as high as
66% [13]. However, the LOI of the ash decreases when the calcination
temperature increases. Ganesan et al. [4] used bagasse ash
with a LOI of 4.9% and found that this did not significantly affect
the compressive strength of the concrete. For classified fly ash,
LOI content increased the water demand of fresh concrete [14].
However, effects of LOI of bagasse ash on the properties of concrete
have not been published.
