Abstract : This study represents the first systematic approach ever undertaken to determine the technical feasibility of using sulphur combined with various types and sizes of natural and crushed aggregates as a structural material. In this program, the engineering properties of sulphur combined with the various single aggregate gradations were determined. Following this, the engineering properties of mixtures of sulphur and fine and coarse aggregates were determined. High early strengths in the range of 4,000 to 6,500 psi in compression were obtained when using a physically poor aggregate such as limestone. The mixtures were studied for workability, and a mix design was prepared such that, in the future, by referring to this mix design, proportions of materials may be selected at will. It was demonstrated that sulphur-aggregate concentrate can indeed be looked upon as a structural material possessing a variety of outstanding characteristics including simplicity of formullation, ease of preparation, insensitivity to ambient temperature conditions, and high early strengths. In addition to this, these mixtures are low in cost and have the potential of being broken up, remelted, and used again upon completion of their useful life in a given application. (Author)
