A process for making calcined gypsum in slurry or powder form. The process includes adding at least two types of crystal modifiers to the slurry. The first crystal modifier is to control crystal morphology of the calcined gypsum (such as succinic and/or malic acid). The second crystal modifier is to prevent or retard setting to control set time (such as tetrasodium pyrophosphate (TSPP)) to form a water stable product. An accelerator is typically added at the site of use for specific applications such as setting type joint compound, media casting, exterior/interior coating, and sprayable fireproofing. A composition made by the process and a kit for using the composition are also disclosed.

L'invention concerne un procédé de fabrication de plâtre sous forme de suspension ou de poudre. Le procédé comprend l'ajout d'au moins deux types de modificateurs de cristaux à la suspension. Le premier modificateur de cristaux consiste à réguler la morphologie de cristaux du plâtre (tel que de l'acide succinique et/ou malique). Le second modificateur de cristaux consiste à prévenir ou retarder la prise pour réguler le temps de prise (tel que le pyrophosphate tétrasodique (TSPP)) pour former un produit stable dans l'eau. Un accélérateur est typiquement ajouté au site d'utilisation pour des applications spécifiques tel qu'un composé à joints de type durcissement, un coulage de milieu, un revêtement extérieur/intérieur et une ignifugation pulvérisable. Une composition préparée par le procédé et une trousse pour utiliser la composition sont également révélées.
