Abstract

En una primera realización de la presente, la brushita madurada se combina con sulfato de calcio hemihidratado y agua para preparar una suspensión de yeso. La suspensión de brushita madurada se comporta de manera similar al sulfato de calcio dihidratado ya que actúa como cristal germen e inicia rápidamente la cristalización. La suspensión de brushita no requiere la adición de un revestimiento para mantener su actividad a lo largo del tiempo en comparación con los aceleradores de fraguado de sulfato de calcio dihidratado. Una segunda realización es un producto a base de yeso preparado usando una suspensión de brushita como acelerador de fraguado. El producto posee las moléculas de brushita integradas como parte de la matriz de sulfato de calcio dihidratado y se distribuye en toda la matriz.Reivindicación 8: Un método para fabricar un artículo de yeso que comprende: obtener una suspensión de brushita molida; mezclar la suspensión de brushita, sulfato de calcio hemihidratado y agua para formar una suspensión de yeso; formar un producto a partir de dicha suspensión de yeso; y dejar fraguar la suspensión de yeso.
