AMÉLIORATION DES PROPRIÉTÉS DU STUC PAR VIEILLISSEMENT À DES TEMPÉRATURES ÉLEVÉES ET À UN NIVEAU D'HUMIDITÉ ÉLEVÉ

摘要

The invention pertains to a method for stabilizing stucco wherein - a fresh stucco is provided; - water is added to the fresh stucco to obtain moistened stucco, and - the moistened stucco is maintained at a temperature of at least 30 °C for a time interval of at least 30 minutes to obtain a stabilized stucco. The process allows inter alia for an easy adjustment of the activity of the stabilized stucco, which is useful to e.g. adjust setting time of a corresponding stucco slurry. The invention further pertains to a method for producing gypsum plasterboards, wherein a stabilized stucco obtained with the above method is used.
