Question

Quizplus · Accepted Answer

Increased porosity of the gypsum particles makes it necessary to use more water to convert the hemihydrate particles back to dihydrate particles when mixing gypsum products.Because gypsum products require varying amounts of water to wet and incorporate the powder into a workable mixture,it follows that the more water that is used,the weaker the cast will be.A product with less water has a higher density of crystals and is therefore a denser and stronger product.
