TEMA 56.3- REACCIONES DE FORMACIÓN DEL CLÍNKER
Durante el proceso de cocción del crudo, ocurren reacciones:
Pérdida del agua libre de los crudos: T< 200°C
Pérdida del agua absorbida en las arcillas: 100°C < T < 400°C
−
*A T(400-750°C) → Se pierde agua combinada, en forma de 𝑂𝐻
Descomposición de los carbonatos: 550°C < T < 600°C
Reacciones entre fases sólidas: T(500-600°C)
*Se producen reacciones entre los productos sólidos de la descomposición de la caliza y
arcilla, formándose compuestos con bajo contenido de cal (𝐶𝐴 𝑦 𝐶2𝑆 )
Reacciones entre fases líquidas:
*T(1260-1310°C) → Comienza el proceso de sinterización
⇉ La proporción de fase líquida ↑ al ↑ T; Alcanzando un 20-30%
A 1450°C ⇒ se puede formar ya el 𝐶3𝑆
Reacciones durante el enfriamiento:
⇒ Enfriamiento lento: pueden invertirse los equilibrios establecidos.
(ej: se podría descomponer el 𝐶3𝑆, cosa que sería desfavorable)
⇒ Enfriamiento rápido: bloqueo del eq. por solidificación de los componentes líquidos
evitando que el eq. se revierta, por tanto la composición del clínker sería la misma que la que
existía.
