basic sand constituents are generally found on the surface of larger grains. Most of the "strange chemical elements" of foundry sand exist in the very fine particles– those which pass a 140 mesh screen. The Acid Demand Value Test (ADV) is a titration procedure that gives a quantitative indication of the amount of acidic or basic

The Acid Demand Value is the amount of acid required to bring high pH and total alkalinity down to their proper levels. This gives insight to carbonates and salts in silica sand. A high acid demand value can lead to pinhole defects in castings due to the production of CO2 gas and lower the life of foundry sands in cold box systems.

Analysis of Chemically Bonded Sand Used for Molding …
The acid demand value (ADV) depends on the chemical composition of the sand. A catalyst requirement of cold-setting, acid catalyzed binders is selected as per ADV. If sands has ADV about 6-10 ml, it requires large quantity of acid catalyst and sand with ADV greater than10–15 ml are not acceptable for acid catalysed binder systems.
