Determination of pH value
Laboratory tests - Standard test methods Determination of pH value. The pH of the sand is a measure of the acidity or alkalinity of the sand. Generally it is thought that pH is an indication of the extent of contamination of the sand surface and the presence of reactive impurity particles.
Mechanical and thermal methods for reclamation of waste foundry sand
Acid demand value (ADV) A sample of dried sand (50 g) was placed in a beaker filled with 50 ml distilled water and 50 ml 0.1 N HCl; this solution was stirred for 5 min at room temperature. The sample was allowed to soak for an hour, and then back-titration was carried out using a 0.1 N NaOH solution until the end point was reached.
Chromite Sand Testing
The Acid Demand Value (ADV) is a measure of any acid soluble material present in the sand. Certain minerals are not soluble in water and therefore are inert in the pH test, but …
The Influence of Acid Hardener on the Strength and Hot …
To determine the alkalinity or acidity of the base sand and to characterize the amount of contaminants that are soluble in dilute acid, pH test and acid demand value (ADV) test were conducted. The former procedure was performed as described by the AFS 5113-18-S standard 52 applying HI2211 pH/ORP Meter device. The ADV test was …
Double Checking for Changes in Binder Reactivity
The ADV test for foundry sands uses 50.0 grams of sand mixed with 50 ml of distilled of deionized water adjusted to pH of 7, and 50 ml of dilute hydrochloric acid. The sand, water, and acid mixture is stirred for five minutes, then the mixture is analyzed to determine how much of the dilute acid has reacted with the impurities in the sand.
