Abstract

Den foreliggende oppfinnelsen tilveiebringer en fremgangsmåte for fremstilling av en kalsinert gips, hvori blandingsvannmengden reduseres og herdetiden ikke øker. Ettersom rågipsen settes sammen med et materiale av karboksylsyretype og kalsineres, kan en kalsinert gips fremstilles, hvori blandingsvannmengden er liten og herdetiden ikke øker. Videre kan en vanlig gipsplate fremstilles uten å redusere produktiviteten av gipsplaten, selv dersom en stor mengde av resirkulert gips, som øker blandingsvannmengden, brukes som en rågips, fordi blandingsvannmengden er liten og herdetiden ikke øker for den kalsinerte gipsen fremstilt som beskrevet ovenfor.
