Gilsonite as a Carbonaceous Foundry Sand Additive

 Laboratory tests were performed to determine the effect of five commonly used carbonaceous additives on new sand mixes. The additives evaluated were seacoal, pitch, petroleum asphalt, Gilsonite of a "coarse" and "fine" grind, and blown asphalt. The tests comprised evaluating physical properties of new sand mixes at approximately 1% volatile at 900°F (482.2°C) and 40% compactability.Physical sand properties developed with non-seacoal carbonaceous [...]
