The Bureau of Mines has conducted research to devise new advanced construction materials for use in hostile chemical environments where corrosion due to acid and/or salt exposure results in failure of conventional materials such as portland cement concrete. Goals for the research are to reduce maintenance and increase productivity so that industry can improve its competitive position. Materials developed utilize a sulfur polymer cement and include composites formulated both with and without glass-fiber reinforcement.

Material characteristics presented include mechanical strength, resistance to creep and freeze-thaw damage, and linear shrinkage during placement and curing. Glass-fiber additions improved freeze-thaw durability, reduced linear shrinkage, and did not negatively influence other mechanical properties.

Examples of construction repair utilizing sulfur polymer cement concrete (SC) are described for chemical environments encountered during production of sulfuric acid, ammonium sulfate, phosphoric acid, potash, and other fertilizer materials. Results are compared with performance of conventional construction materials.

Sulfur concrete materials do not show any sign of deterioration due to acid and salt corrosion after approximately 9 years of industrial testing.
