Sulphur concrete

Abstract

Sulphur concrete is a relatively new material, and although similar in final appearance to portland cement concrete, its manufacture, handling, use, and testing are different. Sulphur concrete is a thermoplastic material prepared by hot-mixing sulphur cements and mineral aggregates. Sulphur concrete solidifies and gains strength rapidly upon cooling. As with other concrete materials, such a portland cement and asphalt concrete, sulphur concrete is a generic term for a range of products that vary with aggregates, sulphur cements, and proportions used. By using sulphur cement binders and aggregates that are not attacked by many mineral acid and salt solutions, high-strength corrosion-resistant sulphur concrete can be produced for use in certain applications where other construction materials deteriorate rapidly. Sulphur concretes are generally not resistant to alkalis or oxidizers but exhibit excellent performance in many acidic and salt environment.
