ABSTRACT
Sulfur, a thermoplastic material, is melted and mixed with an aggregate after which the mixture is poured, moulded and allowed to harden. Sulfur concrete is not concrete in the traditional sense because little chemical reaction happens between the components. It is considered well established as a building material to resist corrosive environments, or in areas where there is high acid or salt content. Sulfur concrete usually contains 12-22 weight % sulfur and 78-88 weight % aggregate in its composition. The sulfur could consist of 5% plasticizers. The aggregate may include coarse and fine particles. Sulfur is generally expected to melt at about 119◦C and stiffen above 148◦C; therefore, the sulfur and aggregate must be mixed and heated at a temperature between 130◦C and 140◦C. Thus, the environment in which sulfur concrete is used must not have a temperature greater than the melting point of sulfur (Vaniman et al. 1992).
