acid demand phchromite sand testing

The ADVtestfor foundry sands uses 50.0 grams ofsandmixed with 50 ml of distilled of deionized water adjusted to pH of 7, and 50 ml of dilute hydrochloricacid. Thesand, water, andacidmixture is stirred for five minutes, then the mixture is analyzed to determine how much of the diluteacidhas reacted with the impurities in thesand.

TheAcid DemandValue (ADV)Testmeasures the amount of basic material present in thesandthat is soluble in a diluteacidsolution. Since the reaction which cures the resin in many chemical binder systems isacidcatalyzed, and since theacidis very mild, the presence of the basic material which can neutralize this weakacidwill retard the curing reaction.
