ABSTRACT:
Sulfur cement-aggregate compositions such as sulfur cement concrete and mortars, comprising a sulfur cement and an aggregate and processes for preparing such products. The composition is characterized by the use of an expansive clay contaminated aggregate, which has been pretreated with a salt solution (e.g., KCl, CaCl.sub.2, etc.). The salt solution pretreatment substantially improves the water stability of the final sulfur cement and aggregate product.
