Corrosion-resistant sulfur concrete materials have been developed for use in acidic and salt environments where portland cement concrete (pcc) materials fail. Industrial testing has shown that these materials are durable in 50 different process environments. The materials exhibit excellent mechanical properties when compared with pcc. Sulfur concrete shows great promise for applications in the chemical, metallurgical, and fertilizer industries. Other potential use areas include marine environments and highway and bridge areas where salt corrosion is a problem.
