Glossary - Euroslag

Molten slag is thrown through the air by a spinning drum and water is sprayed into the area from the sides and ceiling of the structure. Both air and water cool the slag. The smaller particles produced are glassy and are suitable for cementitious use. The larger lumps (greater than 10 mm) tend to be crystalline and thus used for aggregate.
