Resumen

Se ha evaluado la capacidad consolidante del silicato de etilo en tres tipos de ladrillos cocidos a 800, 950 y 1100 °C. Se eligieron dos concentraciones de producto, al 25% y 50%, diluyéndolo en white spirit para estimar si más dilución favorece una penetración más en profundidad del producto o si una mayor concentración produce una mejor consolidación de los ladrillos. El silicato de etilo ha causado una disminución de la porosidad y un aumento de la compacidad de los ladrillos, acentuándose estas modificaciones con mayor concentración de producto. La distribución porométrica no ha cambiado de forma sustancial, disminuyendo los poros más pequeños. Color y luminosidad de las piezas han modificado ligeramente tras la aplicación del consolidante. Los ladrillos consolidados han mejorado su durabilidad frente al envejecimiento acelerado producido por las sales. En general, las piezas más duraderas han resultado ser las tratadas con el 25% de silicato de etilo.
