<p>The invention relates to an improved accelerator for gypsum board manufacture, the accelerator containing a ground mixture of gypsum and a long chain fatty carboxylic acid, e.g. stearic acid, or a salt thereof, to the manufacture of the accelerator, and to its use in gypsum board production. The accelerator is less liable to deterioration on storage than conventional gypsum accelerators, and its use yields gypsum board of improved properties.</p> |
