Composite materials based on sulfur polymer cement (SPC) and mineral aggregate have been developed by the U.S. Bureau of Mines as part of a program to utilize abundant mineral resources. Program goals are to develop durable, chemically resistant construction materials to increase productivity in the chemical, fertilizer, and metallurgical industries by lowering maintenance costs for labor, energy, equipment, and material. This paper describes the research related to development of SPC, the sulfur concrete, and the industrial testing, together with commercial-scale equipment development and large-scale construction practices.
