• Abstract:
  Recent research has led to the development of durable modified-sulphur mortars, concretes, and coatings. All of the methods of using sulphur as a binder for rigid concrete rely on the reaction of one or more modifiers to stabilize, in the hardened state, at least a portion of the sulphur in its less brittle, less dense form. The durability of the concrete produced appears to depend on the modifying system used. In all cases the sulphur must be heated to a liquid state to react with the modifier and to mix with and coat the aggregate and filler. Sulphur concrete can develop high strength, attains strength in a few hours, requires no special curing, resists acids and organic liquids, has no known undesirable reactions with aggregates, and requires no limitation on the ambient temperature at the time of placement. When its use becomes economically feasible, sulphur concrete will be an excellent material for use in pavement repairs and bridge deck overlays.
