Green Sand (Clay Sand) Clay sand is the mixture of natural silica sand, clay, additives and water. The clay used to make wet clay sand is bentonite clay. The compressive strength is generally 0.05 to 0.1 Mpa. The water content is 3.5 to 5%, and air permeability is more than 80. It is commonly used in machine molding and hand molding.

The pH test for foundry sands uses 25.0 grams of sand mixed with 100 ml of distilled or deionized water adjusted to pH of 7. The sand and water is stirred for five minutes before the pH of the water is measured. The detailed method for determining pH of sand is found in The Mold and Core Test Handbook, 3rd Edition, AFS 5113-00-S.
