Abstract:

The plaster is less used as a binder in the foundries due to its mediocre mechanical resistance. The composition concerning the calcium sulfate and carbon dioxide of the plaster is relevant in obtaining a good resistance of the foundry moulds. This paper try to establish the way of determining the values of these two mineralogical components, which assure an appropriate resistance of the foundry moulds made from plaster.

Keywords:

mineralogical analyze, calcium sulfate, carbon dioxide, foundry plaster, mechanical resistance.
