Kinetics of the Reaction of Calcium Hydroxide and Fly Ash
The reaction kinetics of a Type-F fly ash with calcium hydroxide (CH) has been investigated at temperatures between 25°C and 60°C. Thermogravimetric analysis (TGA) was used to determine CH consumption and production of hydrates (non-evaporable water) as a function of hydration temperature and time for various CH/fly ash ratios. The results indicate that the reaction rate, reaction stoichiometry and activation energy are dependent on the CH/ash ratio.
