CONSIDERING SULPHER A CEMENTING AGENT

The properties of sulphur concrete are compared with those of conventional concrete, and the possible advantages and disavantages of this material are discussed. Sulfur may be combined with fine and coarse aggregates to produce a concrete with a strength of 6000 to 700 psi. While sulfur concrete exhibits no shrinkage, a roughly equivalent problem may occur through the thermal contraction resulting as the concrete cools from its crystallization temperature of 240 F to the ambient temperature. Thermal movements of sulfur may be expected to be significant. Work also indicates that sulfur concrete exhibits more creep than Portland cement concrete. Sulfur concrete has an excellent resistance to deicing salts. Admixtures to the sulfur will prevent it from burning, although it will remelt when heated to 240 F. The problem of acid formation under the combined action of sunlight and water must, however, be overcome. Details are outlined of preliminary beam and material properties tests, and some difficulties encountered are discussed. These difficulties relate to the obtaining of a smooth level surface at the top of a beam, the limited mixer capacity, and vertical cracking which occured in the second and third lifts as a result of the restraint provided by the hardened first lift. Preliminary results indicate beam behavior comparable to that of Portland cement concrete beams.
