Hormigón de altas prestaciones, Adición activa, Durabilidad, Difusión, CorrosiónResumen
En este artículo se estudia la influencia en el comportamiento frente a cloruros de la adición de nanosílice (nSi) y microsílice (mSi) en mezclas binarias y ternarias. El principal objetivo es obtener un hormigón autocompactante de altas prestaciones con una alta durabilidad frente a estos ambientes agresivos con cloruros. Se prepararon diez dosificaciones usando cemento Portland (CEM I 52.5 R) y adiciones de nSi y mSi en mezclas binarias y ternarias. Se estudiaron y analizaron tres ensayos frecuentemente utilizados para evaluar la resistencia a la penetración de cloruros, resistividad eléctrica, migración y difusión de cloruros. Tanto las mezclas binarias como ternarias presentaron mejoras significativas en la resistencia a cloruros, en general proporcional al contenido de adición. En todas las mezclas ternarias se ha obtenido alta resistividad, indicando una penetrabilidad a cloruros notablemente baja. Estas mezclas proporcionaron un coeficiente de difusión de cloruros extremadamente bajo, incluso para bajos contenidos de adición.
