Abstract
En el presente trabajo se evalúa el desempeño mecánico del cemento blanco coloreado con pigmento azul ultramar y se explica su desempeño a partir de las modificaciones mineralógicas acaecidas por la sustitución de cemento por pigmento en porcentajes de 5, 10, 15 y 20%. Se fabricaron hormigones y pastas para ser estudiados a 3, 7, 28 y 90 días de curado normal. Se encontró que el pigmento Azul Ultramar al entrar en contacto con el C3A del cemento y el agua, y debido a su contenido de azufre, permite la formación de grandes cantidades de etringita primaria (desordenada y dispersa en la matriz), lo cual se traduce en un incremento de la resistencias mecánicas de los hormigones sustituidos con Azul Ultramar hasta en un 45% a 90 días de curado normal.
