Frac Sand Testing

The sand must be pure to be used for frac sand This can be determined through turbidity testing and an acid solubility test If the sand has lots of impurities, then the turbidity and acid test results will be poor Frac sand needs to be very strong Strength is found using the crush resistance test The crush resistance test is used to ....

Acid Demand Value (ADV) Test Kit

The Acid Demand Value (ADV) Test measures the amount of basic material present in the sand that is soluble in a dilute acid solution Since the reaction which cures the resin in many chemical binder systems is acid catalyzed, and since the acid is very mild, the presence of the basic material which can neutralize this weak acid will retard the curing reaction...

Acid Demand Test

Acid demand tests are also useful prior to testing pool water pH when the pH level is suspected of being extremely high The acid demand test will indicate how much acid to add to the water, which after adding and allowing time for the water to readjust, the pH can then be tested more reliably...
