The primary purpose of this investigation to study the feasibility and effects of sulfur impregnation of concrete carried out at atmospheric pressure. The investigation had three parts: to study the effects of process technology parameters (mix proportions, time of curing, temperature of drying and time of immersion in molten sulfur bath), to analyze the effects of high temperature and temperature cycling on properties of impregnated concrete, and to explore the possibility of improving strength and ductility of SIC by addition of steel fibers. I t was observed that sulfur impregnation can increase flexural and compressive strengths, and elastic moduli from about 2 to 5 times depending upon the various process technology parameters. Near optimum improvement was attained for the types and sizes of concrete specimens used in this investigation when they were moist cured for 24 hours, dried for 24 hours, and immersed in molten sulfur for 24 hours. Sulfur impregnated fiber reinforced specimens showed high flexural strength (up to 4,000 psi) and substantially improved ductility.
