✦ Synopsis

Surfur concrete is a thermoplastic mixture of elemental sulfur with a fine and coarse aggregate (I). In order to be prepared, it must be heated above the melting point of sulfur, (llg°C for yellow sulfur (2)). At this temperature, sulfur liquifies and lubricates the aggregate and converts it into a plastic mixture.

On cooling below the melting point of sulfur, the sulfur immediately solidifies and binds the aggregate into a hard, concrete-like material (1). Because sulfur is the binding agent for aggregate, it replaces the cement and water components of a regular portland cement concrete mix (3).

Much of the success of sulfur concrete depends on our understanding of its durability in different environments and on rapid development of material and performance specifications to speed acceptance by government and industry (3).
