calcium-alumino-silie glass and a wide variety of crystalline phases in addition to those found in low-calcium fly ash. Some of these crys-talline phases will react with water and this coupled with the more reactive nature of the calcium-bearing glass makes these fly ashes react more rapidly than low-calcium fly ashes and renders the fly ash
