✦ Synopsis

Different analytical techniques were used to study the hydration of a Class C fly ash in the presence of various concentrations of calcium nitrate. Calcium nitrate was found to accelerate the hydration of calcium aluminate phases in relationship to dosage. Hydration mechanisms were modified resulting in altered products, The new products consisted of calcium aluminate hydrate and nitrate. Evidence suggested that the modified nitrate-hydrates competed with or inhibited the formation of calcium aluminate sulfates hydrates.
