Nuevos clinkers de cemento belitico de cenizas volantes, de la combustión del carbón de alto contenido en cal y cemento belítico

Abstract

Nuevos clinker de cemento belítico de cenizas volantes, de la combustión del carbón de alto contenido en cal y cemento belítico. Clinker formado mayoritariamente por la fase alfa prima de baja temperatura (α' L-Ca2Si04) del silicato dicálcico, que contiene elementos como Fe, Al, Mg, Na y K que le confieren mayor reactividad. El cemento belítico formado por 100% de dicho clinker, se caracteriza porque durante su hidratación produce mínimas cantidades, de Ca(OH)2 asegurando una buena durabilidad del cemento en los ambientes agresivos en los que el Ca(OH)2 forme reacciones expansivas, como es el caso del ataque por sulfatos. El curado acelerado, de los morteros fabricados con dicho cemento, a temperatura igual o menor a 40ºC y el empleo de aditivos reductores de la demanda de agua aceleran la hidratación de la fase belita, alcanzando a los 7 días valores de resistencia mecánica equiparables a un cemento Portland convencional.
