Alkalisilica reactivity (ASR) of most reactive aggregates can be conrolled with the use of certain SCMs. Low calcium Class F fly ashes have reduced reactivity expansion up to 70 percent or more in some cases. At optimum dosage, Class C fly ash can also reduce reactivity, but at a low dosage, a highcalcium Class C fly ash can exacerbate ASR.
