Abstract
Sulfur cement-aggregate compositions comprising sulfur cement, aggregate, and an amount of a phosphoric acid effective to improve the resistance of said compositions to freeze-thaw degradation. The compositions are prepared by the admixture of phosphoric acid to the molten composition or a component thereof. The compositions can be used as mortars or concretes depending on the particle size of the principal aggregate component.
