Dado que el contenido org\u00e1nico puede afectar negativamente al proceso de hidrataci\u00f3n del cemento, el resultado de la prueba puede determinar directamente la idoneidad del material para las mezclas de hormig\u00f3n. Esta prueba se define en las normas TS EN 1744-1 y ASTM C40. Durante la prueba, se mezcla una muestra de agregado fino con una soluci\u00f3n de hidr\u00f3xido de sodio (NaOH) 3% y se deja reposar durante un periodo de tiempo determinado. El color de la soluci\u00f3n resultante se compara con los colores est\u00e1ndar de la escala de colores de referencia. Si el color obtenido es m\u00e1s oscuro que el color de referencia, se considera que la muestra contiene materia org\u00e1nica. La escala de colores de referencia consta de colores estables preparados en tubos de plexigl\u00e1s duraderos.
